For a gambling platform to have a lawsuit does not mean that the casino is not good for other gamblers to use and make bets. Lawsuit is a normal thing as this business may concern because I don't see anything wrong for a company to have a lawsuit or a matter in the court. Same thing happens when stake was taken to court and many were think of reducing the rate at which they make bets on the platform.
Lawsuit is not common in online casino because the only way customer will file a lawsuit is when he is confident enough to his case. Typical issue of the casino always solved via the forum, 3rd party gambling arbitrage or Curacao report. What common instances is casino always have an active scam accusation in the forum.
A lawsuit will automatically junk if there’s no basis on the case. So if the casino has a an active lawsuit therefore something is really wrong. But on this case. OP is just full of BS because he can’t provide any evidence for having one. I doubt too that he will waste money on lawsuit while his case is very obvious against casino terms and conditions for doing double same bets to rigged the casino.
Maybe it is common but we are not aware of it because our forum has no section for lawsuit, just a scam accuse. The number of scam accuse is more than the lawsuit because it is easy to post it and it was only free but lawsuit has a big money involved and the only one that can do it are the whale gamblers because they can gamble huge amounts.
I totally agree on what @Desmong said. Not all sites that has a lawsuit are now dangerous to access but maybe there is only a miss understanding between the player and the casino owner. We can just continue playing there are long as the site is still proven to be legit and the lawsuit issue will just be resolved later on. Stake got a lawsuit too before but they are still standing strong.
