I am working on a curated database of proxy IP addresses frequently used by bots: https://deviceandbrowserinfo.com/product/proxies-ips So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources. I also made an open-source proxy IP block list b…

HN discussionInteresting article. I’ve been curious for a while about how residential proxy IPs are collected too. Many come from shady browser extensions or mobile apps, especially free VPNs (wink wink Hola VPN). People often don’t realize they are turning their device into an exit node.

HN discussionI tried running the hello-mochi.ts and just modified the URL and removed the session closing: - Trying to navigate to ` https://deviceandbrowserinfo.com/are_you_a_bot ` crashes it for some reason - Trying to go to ` https://grok.com ` and the page doesn't render I wished it actually worked because I use my own hand-rolled thin-wrapper over CDP and I would love for a more robust solution to avoid being detected, but…
