everyone screaming about sophisticated detection algorithms (like they're magic) but heres my 2 cents based on 8 months of testing. 98% of 'detection' is just your proxy provider selling you garbage pools. ran tests on 3 'top tier' providers on a high-traffic target site (avg 15k req/day). provider A - flagged after 2k requests, provider B - flagged after 500, provider C (the cheapest one actually) went 3 weeks before a single captcha. so muuuch for price = quality. the detection game isnt what you think (its just bad ips).
