You can't prove it with 100% certainty either (there's always the brother/sister/spouse/mother/dog/goat excuse) so the whole exercise is quite pointless. All we can do is try to audit Sportsbet's multi-account detection by demanding proof from them but since that has privacy implications and it wouldn't convince anyone who thinks that Sportsbet is lying (faking the proof) - I don't really see much use for that.
I didn't check their ToS lately. Do they have "one account per IP/houshold" rule?Multi-accounting enables people to get giveaways & free bets etc multiple times. I’m pretty sure people could cheat at stuff like the poker nights they have. You could be playing with 5 or 6 accounts & clean up? I’ve seen people moaning about it before.
Was this the case here? How is that they didn't spot multi accounts before player won, but as soon as they start withdrawing...."peanuts", SB investigated account? Oh, wait, never mind
