talking about suspicious activities, I have often seen in the totes of many casinos talk about suspicious activities, but in the same totes of the casinos they do not talk in detail about what exactly they consider to be suspicious activities and in case any account is detected any suspicious activity what kind of evidence the casino will show the customer and also the types of punishment the casino will apply, if the casinos gave details about this it would have saved people a lot of headaches. but unfortunately many casinos don't do this, and the reason they don't do it in my opinion is because many casinos use their TOS as a weapon
for example a person deposits $1,000,000 in the casino, at that moment the casino will not ask for kyc and will not detect any suspicious activity, so that person plays in the casino and loses all money, the casino will not ask that person to kyc and will not accuse that person person of having done something suspicious, but if the same person months later deposits 1,000,000$ and plays in the casino and wins something like 3x and keeps 3,000,000$ and then withdraws the money, then at that time kyc will be asked and when will this person hands over their documents and everything is fine, then the casino will use its most reliable and accurate weapon, the TOS and not all, the casino will accuse the customer of having done something suspicious
and the casino will not show evidence of what the customer is accusing, the casino's argument is that they cannot show evidence because that would expose the system that the casino uses to detect cheaters, so that person's funds stay with the casino, this happens a lot in new casinos, and even with some established casinos. unfortunately we do not have a company that moderates conflicts of this type, a third party that would be reliable and that the casinos would show evidence and thus have more transparency in this market
I doubt the casino will go into detail about what suspicious activity the casino has found, especially if you ask about it at support. They will only say that they found suspicious activity carried out by a gambler so they are forced to ask for a more complete clarification from the gambler, including asking them to do KYC if necessary. And if the gambler really didn't do anything that he was accused of, he can do KYC to prove it. If he really didn't do the things that he was accused of, the casino should immediately process his KYC and approve the verification and process the withdrawal of money. But if that happens in a shady casino, the casino will still not do anything and will even freeze the gambler's account so he can't do anything and the gambler can only complain about the problem without any resolution.
If the deposit was made by someone who just joined their casino in the past few days, it would obviously raise the suspicions of the casino so that the casino will ask him to do KYC. The gambler shouldn't do something like that because depositing a lot of money in a casino where he is new will raise suspicions and it is better for him to avoid it first. He has to wait until at least a month or so not to deposit big money and only make small to mid deposit or he can increase his deposit gradually so the casino doesn't suspect him. But the casino will still ask him to do KYC verification if he exceeds the limit in the casino because it has become a kind of obligation that the gamblers must fulfil.
In this case, the casino has the authority and not a third party because it has nothing to do with it. But it happens more often in shady casinos because they will easily accuse their customers of activity and have to go through a thorough vetting process which can take up to weeks. This makes its customers feel uncomfortable because they have to wait a long time and even though they ask the casino the same thing through the support service, their answer is the same and they are told to wait.
