However it's certainly possible that an account might get flagged in error by an automated system or something like this.. No?
I guess so. But what exactly does it mean, that OPs account was "closed"? Is he prevented from playing, but he can still log on and withdraw his funds? Can he neither play or withdraw, until some kind of review has taken place? Or is it really permanently closed with funds siezed and no chance to ever reopen it again? Or maybe closed but with funds returned?
This is not really clear from the post. And also the claim, that "no explanation was given", is highly dubious in my opinion. When Youtube decided to close my account, they did give a reason, it was just not very usefull. It was something along the lines of "you have broken our terms and conditions, you can read the terms and conditions here".
I honestly to this day have no idea, what exactly I did wrong, but some sort of explanation was given. And I simply can not belive, that an online
gambling site would close someones account without at least sending them an email, which even in the broadest possible terms explained why. So I suspect, that an explanation actually was given, but that it was just not very usefull or not one, which OP liked
