See Barney? That's how I feel right now.
Just as a public service, since I've spent all day dealing with this shit, ( here's some tips. )
winter_baby and bellanut, I've checked your galleries and so far I haven't seen any signs of them being hacked (hacked galleries have a row of black characters at the top and bottom. Also, my script blocker pops up), but you might want to take the preventative measures I listed under the cut. Also, winter_baby, the original FNL gallery has been compromised, so I'm just going to delete it entirely (I only say this because I noticed you hadn't uploaded the caps for episode 2 yet, so you might want to do that).
Right now, the galleries that are affected are offline or the directories renamed (another side-effect seems to be that I can't log into some of them to take them offline). So far, I've only restored some of the smaller galleries, like Eureka, The Black Donnellys and [spooks], but I hope to get vm-caps and the movie gallery up and running tonight.
Wow, this sure is FUN. /sarcasm
