Unfortunately, the baseless scam accusations in this forum are in most cases more like false rape accusations/charges. They go unpunished when discovered that they are false, and this goes at the expense of a service's reputation.
The good thing is that members in the forum usually first request for proof from the accuser before they can act.
If accusers turn to silently or disappear in the forum after they created scam accusations and got request from community to provide more details and proofs, it's not good signal for their legitimacy at all. They can disappear by many reasons but a most common reason is they are just trollers, and they know that their fake scam accusations will fail here, so they decided to leave silently.
Otherwise, if the case is not resolved by the casino, that user must come back here for further complaints and surely will provide more proofs.
