I recently started a phpBB forum. It looks like the spammers found me over this past week, because I am getting about 2 spammers registering a day. I have visual confirmation & email verification enabled, so it has to be real humans. It seems all they want to do is fill their profile with their junk links (for obvious reasons), but it is still %$^#% me off.
What is the best way to combat this?
I don't want to turn on the admin approval option, because I feel this deters legitimate sign ups. Is there a way I can ban an ip range? Will this have a harmful effect on legitimate users?
