I noticed that a spammer had posted a bunch of crap in the gallery under picture comments. I've deleted the users, comments, and banned those particular usernames so hopefully this will be an isolated incident. I will hand it to whomever as they did actually have to put a bit of effort into the process. They did physically have to register and were in the database as "real" users so it wasn't any kind of "spam-bot" that I've heard of. If these things start happening more frequently I may have to make "Photo Gallery" registrations require admin "approval".
