Here's kind of an update. Ever since I shut down registration on the old board, someone hacks in about twice a week and it's like they do it just to prove they can. I was actually in the midst of turning the forums one by one into archive-read only forums and the creep struck again.

What I've discovered is it seems the person or persons hacking and spamming the board have to use "<>" to bracket the name they choose to post with. Like say "<hacker guy>" and they get in. I don't have a clue how they're doing it, but I thought I'd let you know.
