Im pretty aware that most of the problem that people had with Rollbit right now are related to their sportsbook. Probably some people find some loophole on it then most decided to abuse it whatsoever so its fine as long as you dont really abuse anything
To some cases they have responded in this thread as well on scam accusations board also specifying the problems but if gamblers keep abusing the rules team won't help them in that cases and have right to block accounts or if sportsbook provider limits up your account.So playing legitimately on your end would definitely help you to avoid lot of problems.
