The service itself worked while keycaptcha.com was down, I checked, so that wasn't the issue. My point was simply that installing KeyCAPTCHA didn't seem to make much difference as far as I could see, though granted I've been using it for less than a day now. Obviously I intend to leave it up for at least a couple of weeks to see how it performs.
It would be more than a little odd if we had manual signups BEFORE installing KeyCAPTCHA as well as after. Since before installing it, the spammers could easily have used Xrumer or various other spamming tools at their disposal without needing to do it manually.
