I added a little text verification thing at the bottom of the registration page (where you have to retype letters on top of an image). This has decreased the amount of spam signups, ie bots that have links to bestiality, incest, etc sites in their profile. I tried doing some IP banning, but it isn't that hard to spoof IPs...
Just thought I'd bring it up in case someone was wondering why person 128 is the 79th registered user. To my knowledge we haven't removed any legitimate users.
