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.
To many case like this so its good to ignore those troll so that we will not feed up their ego to do the same on other platform. We only entertain those legit accusation with valid proof since this is more worth it to lend some attention.
I also doubt Rollbit or any successful casino will ruin their reputation for just like that since they could earn more revenue for providing good service rather than doing some shitty things out here. Many people still believe that this casino is still a one of the best casino exist so unless people think this way then they are still fine.
