Perhaps on some rare occasions where casino decide to go trough accounts of all customers but usually it is withdraw button which triggers fraud team, who knows...
I still stand by "if you accepted bet, pay what you own and then block account(s) if you want to".
I disagree. If you place a bet knowing you are operating outside of the TOS, you forfeit all right to any winnings. Personally I feel anyone caught multi-accounting and breaking the TOS that gets back their deposit or bets is lucky.
Banning these abusers and returning funds, really just encourages them to give it another try. For that reason as well I don't think these businesses should be providing any extra information regarding their processes. They are either a trusted site or they aren't. This doesn't mean they shouldn't respond to complaints but people need to either believe them or not based on what they provide and act accordingly.
And to think the OP did all this for just 21 mBTC which at the time was around 200€ even though Sportsbet had already returned their original deposit of 427 mBTC.
I have no idea why the OP played this game with forum members and with Sportsbet.
They do so because they see an opening. Probably not entirely related to the fact that there was trial run at forum members performing binding arbitration, but could be why it's so heavily weighted to sportsbet. So if you are a multi-accounting scammer, why wouldn't you take a hail mary that doesn't cost you anything but a few minutes time, and barring undeniable evidence gives you a shot recouping fraudulent funds.
It's pretty rare someone goes "Oh well, you got me. I'll go away"
