Yep, I know someone who buys “ID’s” as part of a set up to open new accounts. This is going back quite a few years ago now, but the going rate was $500.Had a friend whose job for a while (while finishing his phd) was a third party putting on bets for a gambling group. He would effectively sit in the pub/tab for hours a week and then put on bets when ever he got the call. He would effectively just pump in as many bets as possible, that were under a certain $ cut off point, until the market would get closed. There are so many systems out there to try and exploit the market while the companies would try and close every loophole they could see. He also helped to "buy" sports betting accounts off people who didnt use them so they could play arbitrage between companies until they would all eventually get locked out.
He now works for Sports Bet writing models for various sports
