What happened to UofL3000?

UofL3000 was one of my best buds on this site.  I noticed that a lot of people have the avatar saying to "Free UofL3000".  I went onto his profile and I found out that his account had been deleted.  There is a group by the name "Free UofL3000" and it said that he screwed up, but he apologized, and that a lot of people want him back.  What did UofL3000 exactly do to get banned from eBaumsworld??  He was one of the top contributors!
