I used to hack obsessively and spam a lot in the lobbies. I would usually make like 3 accounts at a time but at any given time I would have like 10 or so accounts that were active. When 1 would be banned for hacking or spamming the others that were made WITH it would be banned very shortly after. The remaining accounts were left untouched. Maybe that will fill you in on how they work.
