It was falling behind. The dodgy stores were getting more creative and Fakespot needed to play catch up.

You've got stores that would include a $5-$20 coupon/gift card in the item in exchange for a positive review. Sure, this didn't 1:1 translate but if a user did it would look like a legitimate review.

You've got a plethora of LLMs out there just itching to GENERATE.

Then an expensive option I was suprised happened - I bought a Dyson clone vacuum cleaner off of Amazon. A few weeks later, the company emailed me and said 'We have a new model. Buy that one, leave a review, we'll refund the purchase'. So I did it. This happened about 10 more times in 2024. My outdoor shed is entirely stick vacuums.

Feel a bit dirty doing it but that's ok I've got 12 vacuums that can clean my conscience.

I think Fakespot would have difficulty with all 3 of these scenarios.

Some company paid be 100 bucks to change my review to be positive so they sent the money via PayPal no problem then I changed the review to say they paid me to write a glowing review and of course Amazon ended up removing the review for being harmful to their customers

Amazon is awful when it comes to striking down accusatory customer reviews.

Last year I (like a fool) purchased some chunky thru-hole MOSFETs on Amazon. Lo and behold, despite the datasheets promising a few amps with 3.3V at the gate, I only got a few milliamps. Obviously counterfeit - but no matter how hard I tried or how much indirection I employed, Amazon always took down my review warning others of this verifiable fact.

Amazon is not the place I'd go to for electronics parts. Mouser and Digikey are my go-tos.
colonial · 14m ago
Yeah, I'm generally aware of that - but I needed them fast, and decided it was worth taking a gamble. (I did at least get a return/refund, so there's that.)

Amazon are becoming like AliExpress and Temu. They can always do it cheaper, but the quality is touch and go. Now with fake reviews it alot harder to tell what's good quality and what's not.

I prefer eBay at least it’s cheaper and the sellers care about reputation

So they _can_ do something about fake reviews.
dawnerd · 1h ago
They can but they won’t. My original review was still there (as in was included in my updated review) saying how it was fundamentally flawed and will break. Was some video tripod with this dumb mechanism that would work itself loose by just panning. Never seen anything like it.

Plus side looks like the product doesn’t exist on Amazon so guess there’s a victory there somewhere.

I can understand going for the "free upgrade" the first time around, but why continue racking up more vacuum cleaners after that? Do you plan to sell them later?
lt_kernelpanic · 38m ago
Obviously, the plan is to eventually collect enough to construct a Dyson sphere.
dankwizard · 1h ago
You sound like my wife. I don't know. I grew up kind of poor and my mindset still has a "If I can get an item typically worth $100-200 for free, TAKE IT".

The plan was to flip them on FB market place but I've just hoarded them.

It’s the rational option if someone is giving you something for less than it costs you and the moral implications of the action is minimal (at best).

Sure, but consider the costs of consuming your space with junk. Now you have less room for things you care about, there's a maintenance burden, and there's a mental burden as well

Leave honest reviews (not saying you're not) and don't feel dirty. You'd actually be helping.
chrischen · 1h ago
When you have extremely generous return policies then reviews matter less. They are still relevant if your'e trying to optimize for buy once for life, but in that case you should just be going for established brands instead, where their reputation is their review.

> Mozilla couldn't find a sustainable business model for Fakespot despite its popularity

I don't know if it's fair for me to armchair quarterback, but still - what was their business model when they decided to do the acquisition? From the outside looking in barely did anything whatsoever.

I browse Amazon using Firefox extremely often and I don't recall seeing any helper UI pop up. Even so, what would have been their strategy to monetize me? User data? Commissions? Some kind of Mozilla+ subscription?

I love FF and cheer Mozilla on where I can, but honestly these decisions are inscrutable.

burnt-resistor · 5h ago
Mozilla seems infected by corporate board members who probably have conflicts of interest including investments in Amazon, Google, etc.

They could have slid in their referral link, which would probably make them decent money, but the "ick" factor is pretty high from consumers.

I'm sure there will be a replacement though, and I'm sure they will go hard with referral links.

colinbartlett · 3h ago
I recall seeing the Mozilla Review Checker pop up on Amazon shortly after I started using it as my daily driver.

I dismissed it quickly because fake reviews is not a problem I have. Maybe I'm not the target market? I do buy a lot on Amazon but can't recall ever thinking I felt burned by fake reviews.

Mozilla wants to be the "web you can trust" brand, which involves not just shipping a browser but protecting people from the rougher sides of the internet.
zdragnar · 32m ago
I think this is the real answer; they've got a vague mission statement, they saw something they wanted to support, opted to buy it, and in classic Mozilla fashion let it squander because the managers in charge moved on.

It's a move straight out of Google's playbook, with the glaring flaw of them not being Google, and their user base likes them for not being Google.

Honestly, Mozilla gives me gnome vibes. They're so caught up believing their own spiel that they don't understand why they keep missing the mark.

Digory · 14s ago
I’d guess the idea was about generalizing the team’s efforts to spot fakery across the internet, in-browser. But that horse has left the barn.

Before AI, a lot of search result gamesmanship looked more like bad Amazon reviews. But leading-edge fraud is far past “humans pretending to be real, U.S.-based consumers/posters on a website.” The tools don’t generalize anymore.

I did search around looking for alternatives and the landscape isn't great. There's ReviewMeta.com which doesn't work 100% of the time and is no longer actively maintained as far as I can tell.

TheReviewIndex.com I didn't find to be very helpful, as it doesn't index all products and sometimes just refuses to check on listings you ask it to. It seems to have some kind of subscription model, but they don't list the price and offer some kind of enterprise model that doesn't sound like it has anything to do with checking reviews.

SearchBestSellers.com isn't for checking individual products, but it will show you the top sellers for each category so you can get an idea of what could be good in the category you're looking for

Camelcamelcamel.com is a price watch tool that will also show you some historical info on a product & notify you if you sign up and want to be emailed when a price drop occurs

There are a few others on AlternativeTo that weren't there the last time I checked. https://alternativeto.net/software/fakespot/

On Reddit, some people were mentioning alternatives, including asking ChatGPT about the product and it might have some kinda helpful advice, but nothing like Fakespot offered. https://www.reddit.com/r/firefox/comments/1ktm4g4/now_that_f...

If you use something else, have found a good alternative or a particular prompt you've tried in your favorite LLM to get info on an Amazon product, let us know!

doppio19 · 4h ago
I mentioned it briefly in the blog post, but this is exactly what I'm working on! Essentially, a spiritual successor to Fakespot that combines LLM analysis, more traditional ML techniques, and rule-based heuristics to detect fake reviews. I'll likely go the "subscription with generous free trial" route, to avoid meeting the same fate as Fakespot.

I'm actively working on a prototype and have a landing page at https://www.truestar.pro if you want to get notified about when I launch.

Mtinie · 1h ago
Please help me understand why a subscription to your service should be a valuable addition to my monthly spend.

I buy extensively from Amazon across a number of product categories. My order history shows purchases as far back as 2005 (though I cannot be sure given I remember buying things in 1998 while in college, probably on a different account). During the intervening 20 years I can count on one hand the number of products I ordered which weren’t legitimate, matched my—admittedly moderate expectations for any commercial product—or included overhyped reviews.

I’d be interested in a service like yours if I could understand how the cost would cover itself in benefits.

pogue · 2h ago
I saw that actually. I mentioned in another post on here recently that I figured that the only way a Fakespot v2 could exist is with a subscription model, but on the other hand, it's probably not something I could afford. Good luck with it though! You could always try advertising & affiliate links as a test to monetize the service as well.
doppio19 · 2h ago
Thanks! Advertising is certainly a possibility, though I'm not sure using affiliate links in the browser extension itself will be an option. I know Google recently changed their policy on how browser extensions can manipulate affiliate links after the Honey scandal: https://www.theverge.com/2024/12/23/24328268/honey-coupon-co...
pogue · 1h ago
Yeah, probably not in the extension itself. But, Fakespot, on their web based reviews, had listings to alternative or better rated products than the one you were searching for. Possibly a bit of a conflict, but as far as I'm aware, it's the only way Fakespot was monetized.

Solomoriah · 3h ago
I sell books on Amazon.com through their KDP Direct platform, and I have one book with two different covers; each is its own "book" in their catalog. FakeSpot repeatedly marked reviews I knew were valid as fake; I knew this based on the fact that the same reviewer reviewed the "other" book and that review was NOT flagged as fake. And this happened multiple times, and sometimes the wording of the two reviews were different. Further investigation showed FakeSpot had rather a poor reputation overall due to too many false positives. Good riddance, as far as I'm concerned.
kirykl · 37m ago
I have managed some Amazon product pages, which I know have never used fake reviews. Fakespot consistently had false positives for these items
doppio19 · 2h ago
That's interesting! Did you have any guesses as to what might have been setting it off to mark those reviews as false positives?
quitit · 50m ago
Some online retailers (such as galaxus for those in Europe) include return statistics on the sale page against comparison brands as well as price history graphs. This helps stamp out two of the core complaints about amazon: fake reviews and fraudulent discounts.
zdragnar · 39m ago
If you look around, you'll see products on Amazon occasionally marked as "frequently returned". It has steered me away from a few purchases.

Unfortunately, they haven't really countered the "keep creating new accounts" drop-shippers. Some categories are especially bad about this- if you find a back massager that you like, buy it in bulk right away, because the model and probably seller won't be around by the time you want another.

doppio19 · 8h ago
For the unfamiliar, Fakespot was a browser extension that flagged suspicious product reviews on sites like Amazon. Mozilla bought it just two years ago and integrated it directly into Firefox as their "Review Checker" feature. Today, to my dismay, they're sunsetting it. As someone building in this space, I wrote about Fakespot's history, the problem it solved, and why we need sustainable alternatives.
rasz · 6h ago
Did Mozilla score some absolutely unrelated deal with Amazon by any chance recently? They killed DeepSpeech very same day NVIDIA paid them $1.5mil
doppio19 · 6h ago
Not that I'm aware of. But I do know that in late 2024, Amazon made a change where users now have to be logged in to view product reviews beyond the ones that appear on the first page (about 8 reviews). From what I can tell, Fakespot scraped the Amazon product listing pages on their backend, so that simple change would have pretty much killed its current implementation.

With removal of reviews that the seller doesn't like, there's really no point to taking Amazon's star ratings or reviews seriously. It's all a big lie.
SamuelAdams · 5h ago
I’ve started resorting to the “x bought this month” metric instead. If a product works for thousands of people and they continue to buy 500+ units a month, clearly it is a good option.

If it does end up being a bad buy, Amazon typically has a 30 day return policy for most items. Use that and get something else.

derekp7 · 4h ago
They also tell you if a product has a high return rate, which is helpful.
Loughla · 3h ago
Except with clothes and especially belts, I've noticed. It seems like everybody buys three of the clothes they buy and returns two of them. It makes it harder to identify shitty clothes.
dylan604 · 4h ago
How do you know that 500 people didn't buy a scam product this month? I put as much faith in the X people bought this as I do the X people have this in their cart. It's all a way of trying to stoke FOMO

what makes you believe that the number you see in “x bought this month” is not some variant of if (session_is_gullible_to_displayed_sales_number) { return HIGH_SALESNUMBER; } ?

aspenmayer · 4h ago
There’s also the strangely still-not-even-admitted-as-problematic Amazon item page referent shuffle, where one item is for sale on a given page, and the item sold by that page points to one item by a given seller. The reviews of this item are spammed positively, and then the item being sold on that page is changed by the seller, yet the reviews follow the page, not the item sold at the time the review was placed.

This combined with Amazon’s commingling of inventory of Amazon corporate sourced items and third party seller items results in a status quo in which, when purchasing an item on a page operated by the first party manufacturer and/or first party supply chain, the Amazon item picking system may still fulfill that order via inventory sourced by third party Fulfilled by Amazon sellers who knowingly and unknowingly are selling counterfeit products. You never know what you’re going to get with Amazon, and neither does Amazon or the third party sellers. It’s insane.

It sure does get there quick though. And heads back to the warehouse for free if you don’t like it.
aspenmayer · 4h ago
Counterfeit items are contraband and may not be legal to be shipped or mailed, as they are evidence that a crime may have occurred. To return counterfeit items for material benefit to the seller or agent in order to receive a refund is possibly helping the fraud to continue by allowing the destruction of property/evidence. I advise all folks who suspect counterfeit goods to report them to the FTC and their local police department to get a police report, and insist that the police take the item(s) as evidence, then provide the police report to Amazon to facilitate the refund, instead of returning the potential contraband to the contraband dealer for them to sell again or for them to destroy the insufficiently misleading fake item.

Scammers are somehow using Amazon itself as an A/B test for if your fakes pass muster, from what I can tell, and everyone loses but Amazon and the bad guys. How long must this continue?

Is this something you've actually done? You might want to work on your pitch, it comes across as a little crazy haha
aspenmayer · 2h ago
> Is this something you've actually done?

I haven’t done this myself, but I have discovered that it is not allowed to ship or mail items with lithium ion batteries that are likely or suspected to be or actually are damaged, which came in handy when I discovered that a previously working device suddenly stopped charging within the return period. Amazon said I had to work with the seller directly through Amazon, which I did, and when they offered to replace the item and I desired a refund, they refused and stopped responding. I elevated the issue to Amazon and they asked me to return the item, which I was unable to in good conscience do, as I could not attest to the shipper that it was safe to mail, as it had a non-removable battery that would now no longer charge. So Amazon said please don’t ship it, but to dispose of it according to my local disposal regulations.

In the interest of public safety, I told a lot of people about this important issue at my own freebooted unaffiliated DEF CON 30 talk outside while a bomb threat or something caused Caesar’s to be on lockdown. At this talk, I gave away the affected device, a Ledger Nano X which would work when powered via USB C but would not charge or work unplugged. All features and functions still worked otherwise.

> You might want to work on your pitch, it comes across as a little crazy haha

It’s funny you mention that, as I really had to almost haggle to give it away, it was really a kind of comedy routine that occurred to me in the moment, and it was hilarious. Think about the tone of delivery of spam emails. The delivery mechanism itself is worded in such a way that it weeds out folks not receptive to the message. The message is the medium. It’s the multi sensory experience of being appealed to which is the payload that runs on vulnerable processors of susceptible minds, if you ingest it in the way presented and intended.

Thank you for coming to my socially engineered TED Talk re-enactment. I had a lot of fun that year and will be going to DEF CON again this year in a month or so too!

There's a discoverability problem with this tool because I've never heard of Fakespot or Mozilla Review Checker until today.

> Mozilla integrated Fakespot's technology directly into Firefox as the "Mozilla Review Checker" feature, making it easier than ever for users to verify product reviews without installing separate extensions.

If it was integrated directly into Firefox, it's funny that I don't recall ever seeing it. I wonder if it gets disabled if you set your security and privacy settings too high, or if you use the Firefox ESR versions (Extended Support Release).

burnt-resistor · 5h ago
Better than nothing. Not sure how well it worked or if it used any particularly advanced AI similarity checker or sentiment analysis.

It's pretty easy to spot obviously unrelated reviews that talk about or include pictures of completely different products. What's hard to spot is similar reviews written by bots or people paid to write as many reviews as possible using similar language, especially when there are thousands of reviews.

bb88 · 4h ago
The last year it's been a mixed bag.

One issue is that seller warnings would appear on Prime delivered products, which meant that the risk is then pretty much zero for the buyer.

The ratings gradings system wasn't very reliable either. I bought a few things that were rated "F" but were fine.

Today I go for a combination of sales + ratings. Amazon also has a warning for some things that are "frequently returned items" or a notice that "customers usually keep this item." And then I buy Prime delivered items, and a return is not an issue for me then.

doppio19 · 5h ago
I found that it did a pretty decent job. Certainly not 100% accurate, but it often picked up on signals that made me give a closer look at a listing than I would have otherwise.

I'm sure detection is getting harder as LLMs' writing patterns become less predictable, but I frequently come across reviews on Amazon that are so blatantly written by ChatGPT. A lot of these fake reviewers aren't particularly sneaky about it.
