It's mostly people who do not follow the rules and when the casino takes away their money (and most of the time that money is frozen, not spent by the casino) because the user broke the rules, that means that the user will come back here and start to complain here, even some people who did not have a user account here and opens a newbie one just to complain about it only to find out later on that they were the ones who broke the rules.
Rules are clear and bold enough and those users just try to break rules intentionally because they think they are smart enough to outsmart the casino. What do they have at the end?
They only can complain without proof to show that they are innocent and victim. In contrast, the casino has full set of data for user law-breaking activities and when they pull the serious card like account termination, it's serious enough because they don't easily self-harm their reputation. I've seen many cases like this, complain day by day, use bad words and eventually when results are out from customer support, more violations are detected.
I'd like to add that the second user was already explained that they utilize [and by utilize, I mean questionably taking huge advantage of] a feature to 1,000x leverage of one of their "trading" game, already made a huge profit of it from
very small deposit [$99.55 v. 67,009.05]
In that case, Rollbit did their processings for withdrawal of that user a few times, before they terminate his account. Total amount of approved withdrawals is not small as I recall.
and when asked further about why he delibetely abusing their trading feature, he went defensive and start calling anyone questioning him as staff or Rollbit.
It sucks but because he abused the casino, exploited it, he has to end with a failed, invalid accusation.
