fullypak has been an account seller for a longtime, has had neg rep for awhile too and doesn't care. Doesn't care about anything except money. The best way to deal with this dude is try to find out what accounts he is selling and report them.
I don't think he's that stupid to give names to anyone to check those accounts, so it's definitely not going to be an easy task for us to try and find any of his accounts (except he left any clues by using same addresses in some bounties and what not). But based on his knowledge about the forum, I don't think he left any footprints as of yet and you will only know after someone actually buys them and starts spamming with those accounts after joining this campaign. And yeah, a personal hats off for your spam busting services.
