stopforumspam - only email check no ip check.

[treasureman]

With VBstopforumspam you can choose whether or not to use IP blocking via the control panel. Also you can choose whether or not to use email blocking and user name blocking.

I use IP blocking and email blocking, but not user name blocking as that produced to many false positives.

I get almost zero spam registrations. I also use the !NoSpam registration mod instead of the captcha.
