Ever since the latest hack was installed, over 100 ip addresses have been banned by the system (the hack automatically bans the ip address of the bot that tries to add a website in the profile - a normal user can't do that when he registers). I also noticed spamming was reduced a lot, and that we barely have a robotic registration every 2-3 days.
As some of you know, i dissallowed the "website" option a while ago, but with this new hack posters can have a page in their profile after just 5 posts
