That is just the way scammers think, they are so used to getting away with their scams that they are always thinking for ways to scam everyone, and this includes casinos, and while it is unlikely they can get away with their scams for long, for many scammers this is enough to make a living out of it, then the casinos tightens up their security and then we are the ones that have to go through a more comprehensive verification when we did nothing wrong to deserve it.
In this gambling industry there is no firm action against all casinos who often commit fraud, so they will continue to carry out their actions by deceiving many gamblers to be able to take easy and large profits.
If there is a law in the gambling industry that is able to follow up on cases of fraud committed by several scam casinos, maybe in the future there will never be any more fraudulent casinos in circulation.
But I'm not really sure there is a law that can follow up on scam casino cases until now because we can all see that those who are clearly fraudulent casinos can still continue to operate and there is only mention of a bad reputation against them without any action such as closing or removing the name of their casino from the list of crypto casinos.
These are serious problems that have been going on since then and there has been no good resolution about them.
