Hi,

We have a few plugins aimed at stopping spam:

http://www.ultranerds.com/Detailed/133.html (lets you block URL's from submitting, direct from the "validate links" area)
http://www.ultranerds.com/Detailed/173.html (lets you block IP's/IP ranges from submitting)
http://www.ultranerds.com/Detailed/4.html - (adds a CAPTCHA image on add.cgi, so that they have to enter a random string before it will accept - this stops most prolific spammers)

Hope that helps.

Cheers

Andy (mod)
