In business world if their competitor is successful there are entities will try to destroy their reputation so don't get surprise if something like this will exist. As long as Rollbit or any casino is active and reputable high ranking member also with their old time gamblers still trust them well maybe this one indicate that they are still a good casino. If they could just follow the rules and have strong proof on this claims for sure there accused casino cannot escape on their existing case.
Yes we cannot ignore all the accusations as long as they can provide valid evidence then senior users can help them, I often see new users experience almost similar problems with a frozen account like the list of accusations above, it's just that the amount of funds frozen is not proportional to the campaign funds spent by the casino so it's strange if the casino takes risk and interferes with their reputation.
It's not about the new users but problem can be with any account but the part is they register on the forum with new account to open up about these accusations and in most cases it turned out to be that player was at fault raising false claims because they are unable to withdraw now because of their mistakes in case of legit casino.I think these problems will be resolved or already in the progress by the team.
