hp0pach1n0 was some lamer script-kiddie who knew of an permissions bug in the early CGI-driven chat we used. He logged into a non-documented admin account and screwed with everyone's settings causing a shit storm that he seemed to revel in before leaving. He evidently did this to rather a lot of sites running the same software, as indicated by a lot of research done at the time. We have since ditched that program (as it was a horrible bandwidth hog) and moved to an IRC channel.
