Quite simple, because he advantage player.
We all know, that mostly advantage player in "Sportbet" having a limitation fund to be bets (especially, if you are on winning PNL).

He advantage player, getting profit by doing several activity like arbitrage and other & avoiding some limitation bet size fund from his first account by creating another account.
OK, from an unbiased viewpoint, then probably the most he could expect is for the casino to return his deposit minus the profit. But that's the casino's decision.
Plus it's laughable that he/she has the nerve to post in the topic after what he's done. I already put him/her in my ignore list because it's useless talking to him/her. He merely needs to wait if Shuffle decides to give him/her his deposit back.
