so, everyone's obsessed with proxies but i see people using them wrong every day. detection isn't about some magical algorithm. it's about mundane stuff like your tcp stack timing and browser fingerprints. ran some speed tests on the big providers and guess what? even residential ones leak patterns if you rotate too fast. i'm tired of the advice to just 'buy better proxies.' looked at raw traffic logs from a test site i control. most proxy blocks come from connection anomalies that basic rotation doesn't fix, not ip quality itself. citation needed on any provider claiming perfect stealth.
