Why blocking WebRTC does not protect against detection

Almost all anti-detect browsers on the market simply block WebRTC, so there is no leak. But that is a red flag too. For most ordinary users WebRTC works, and if it is disabled, that also raises suspicion.

The only correct way is not to block WebRTC, but to proxy it correctly through a UDP proxy, and for that both the browser (or software) and the proxies themselves must support it.
