Re: BuddyPress Spam
I think someone more knowledgeable about things .htaccess could better answer that question. I’m really still learning about all this stuff myself.
About your other idea though… now that could be brilliantly simple! It could sure put one heck of a damper on the efforts of human sploggers who are, if their activities are any indicator, a lazy bunch. Only thing is, it wouldn’t do much for those bots who manage to squeeze through whatever “backdoor” they happen to find (or make).
Anyone want to take on a little “Avatar Required” plugin challenge here?
