We've been getting hit hard by spammers the last couple of weeks - dozens of registrations with signature spams per day. I installed KeyCAPTCHA in the hopes that it'd help - well, it didn't in the slightest. We've had 4 spammer signups in a few hours since installing it. It seems to be the same spammer group as before installing KeyCAPTCHA. I simply can't believe that all this spam is manual.
