Author here: I work in bot detection, and wrote this post to explain why privacy-conscious users (VPNs, Brave, LibreWolf, etc.) often get flagged or blocked by anti-bot systems.

I’ve seen a lot of frustration in threads here, so I wanted to offer a technical perspective on why these false positives happen, and how detection systems interpret signals from non-mainstream setups.
