[geeklog-devel] Anti Spam Features

[Tony Bibbs]

Yeah, obviously you would start by banning anonymous comments.  What I 
was after is the more difficult use case of admins who want to allow 
anonymous comments yet prevent spam.  Good clarification though as, 
obviously, banning a username is much easier and reliable to do than an 
IP.
