2006 April's Fools. The admins make an account called Todoroki and put him as Site Admin. Then "the evil hacker" changed all the themes into a single, completely black one, and put "The Todoroki Community" in the banners. They also make a fake "Mod Lounge" full of posts where the staff discussed things as forbiding signatures. Some admins got pink names, people got randomly banned (with them knowing, yeah), Loki was blamed for no reason (before she became a mod)...
Search "Todoroki" in Community Questions and Feedback and you'll know.
