Every guide, comparison and detector run we have published under detection.
Residential is not automatically better and datacenter is not automatically dead. What actually decides the outcome is whether the proxy is bound to the identity, and most setups get that part wrong in a way that is easier to detect than the IP itself.
Detection stopped asking which fonts you have and started measuring how wide they are. A missing font is not hidden: it renders in the fallback and measures exactly like a family nobody has ever installed. If your persona claims Windows on a machine that is not Windows, that is a one-line contradiction, and no amount of aged profiles or clean residential exits talks you out of it.
A high anonymity score means little. What gets profiles flagged is contradiction between signals, not any single value. A checklist of the pairs that must agree, and how to test each one in a few minutes.
DataDome, Kasada, Cloudflare and PerimeterX do not run one check, they score a risk profile from network, TLS, fingerprint, behaviour and history. Understanding which layer flagged you is the difference between fixing it and guessing.
The most common complaint in this category is that people set up a fingerprint browser and residential proxies and got banned anyway. Usually the tooling was fine. Here is what the tooling never covered, ranked by how often it is the real cause.
