You guys are forgetting the fact that a person can do this multiple times every single day via an automatic bot. I mean we are not talking about someone dealing with this by hand, he probably just gets a small machine like rasberry or whatever and he puts the bot in there and let the machine do the work. So it doesn't really take any time for that person, he doesn't even have to check, all he has to do is build a bot that will do whatever it takes to make money and if it ever reaches a point that it can withdraw, it just sends it to his wallet, so he literally never has to even look at it as long as it really works. Sure maybe he doesn't achieve what he wants and I hope he never achieves it (from what mintdice mentioned they don't achieve it) but it's definitely not taking that much time after the first build is made.
I completely see your point but even if someone was to aim for such a high level abuse then don't you think that maybe this can be monitored from the casino's side. Like only allow withdrawals from deposits or wins. This of course will require regulation from within about where each player's money is coming from but I feel that perhaps the best solution is to tackle it from within. It won't be cheap though it will deal with all of these problems once and for all
It has been a common thing for years from the scammers or basically anyone who makes money in any way that is against the rules to "play stupid" and try to get their money back.
I remember few months ago (or maybe over a year now, I can't remember) there was an account that kept on asking for his money back that he lost because "his kid gambled, and not him" from another casino. That was literally the explanation for it, dude literally said he wasn't responsible for the loss because it was his kid that lost the money and not him, so in theory on his mind that meant equal to someone else gambling from his account like a hacked account since he wasn't the one gambling from his own account. That is literally the level people are willing to go down to make their money back.
