Tor does it by being so painfully slow an unreliable that the only way you would use it is if there is a cocaine-style reward at the end of it.

They get blocked by Recaptcha, I think.

I’m not talking about the network itself but the servers on the other end.

I guess my point is that while Google is definitely malicious, I don’t think every site using recaptcha is and if we expect them not to use that tool there should probably be an alternative.
