I started getting a fresh deluge of spam registrations. I require approval for registrations so none of them get through, it's just a pain to go through them all. recaptcha is useless. Half these come from gmail addresses so of course Google is going to be no help in solving it.

This plugin stopped the spam registrations completely. Yeah, someone could code around it but I've found that using tactics like this that are the exception rather than the rule rarely merits that kind of attention from the spammers.

The only downside is that one of the most common sources for spam registration (besides gmail) is now bouncing these validation emails as spam. The developer said that the email ban list is still honored but these emails are coming from a banned domain so I assume that he must mean that it's still honored in the main registration process. That doesn't help with the bounce problem.
