From the article that was linked in a few posts up: He was running a major spam operation, and he got into a list of known spammers arranged by SpamHaus (an anti spam organization). The list happens to have about 100 people.

It's said that he received a few letters from the FBI and other law enforcements while he was running the operations. Nothing specific.
