This Really Worked!

This is just a compliment, thank you for this simple and absurdly useful module. I've had trouble with registration and comment span forever and registration is especially a problem. I have tried Mollom, I have Akismet, recaptcha, tried I think every module out here to no avail. I also have server firewalls, IP deny, retry timeouts....
spam scripts still get through.

So, I saw this, thought, let's try this and whammo, it's STOPPED! What's even better is this kicks in before using more bandwidth to check with recaptcha, or using Anti-spam more outgoing bandwidth checking on the latest, so it's very useful to do this as a first line of defense in terms of server resource issues.

Thank you!
