I built antidetect tooling since 2015. The failure is almost never the proxy.
The conversations here keep circling back to proxy selection. Which provider, which type, sticky vs rotating. But I have been watching fingerprinting detection evolve since 2015 and the proxy is rarely what causes a working setup to degrade over weeks.
What actually kills sessions is coherence failure.
Platforms do not score individual signals. They score whether your signals agree with each other. A residential IP says "regular consumer in Berlin." Your browser's TLS fingerprint says "modified Chromium." Your canvas hash says something else entirely. No single signal is the problem. The pattern is.
I analyzed over 100 threads on fingerprinting and account bans. The failure narrative is almost always the same: day one works fine, then something quietly accumulates, then everything falls apart at once. The account was not killed by one bad check. The trust score eroded because the signals stopped telling a coherent story.
A few things that changed how I think about this:
Detection starts at the transport layer. If your TLS fingerprint marks the connection as automated before the page loads, the JavaScript checks do not matter. The decision is already made.
Proxy to profile coherence matters more than proxy quality. A residential IP paired with a browser profile that expects a different locale is not a coherent setup. It is two contradictory signals pointing in opposite directions.
Randomization is not the answer. A fingerprint that randomizes every field contradicts itself. What survives over time is a setup where every layer tells the same story.
The question worth asking is not "which proxy provider should I use." It is "what story are all my signals telling together, and do they agree?"
Curious if others have mapped out which signal mismatches tend to surface first in their setups?
