been reading these threads for a decade and I'm tired. The advice is always about IP rotation speed, subnet quality, fingerprint spoofing. That's the machinery. It's not how you get caught. Sites don't catch your proxy, they catch the human pattern your script or bot fails to mimic. Back in the day with simple social media tools, you could brute force it with any residential IP. Now it's a behavior layer on top. Think about it like this. You set up a perfect rotating residential proxy pool, anti-detect browser, the works. You go to scrape or post or whatever. The first thing that flags you isn't the IP. It's that your mouse moved from point A to point B in a straight line at a constant pixel speed every single time. Or your requests happen at perfect 2-second intervals for 8 hours straight. No human does that. The real leak is in the rhythm, not the mask. I see people burning cash on premium proxies while their automation acts like a robot wearing a very expensive hat.
