Guy brags about having 3 accounts at Poker Stars

[esknights]

Sitting at a table today and a couple of players start talking and the one says he signed up for 3 accounts on three different computers and currently uses all 3 on Poker Stars.

I thought Stars was pretty good about preventing that sort of thing.
I guess he could have set up 2 extras for his "mom" and "sister" and then it would be pretty hard to detect.

Thoughts?
