Because how many customers will complain publicly?
Not many and even less will finally get a refund.
Some customers will just write a negative review, walk away and Casino or Gambling site will keep all profits.
Besides necroposting, and not being on point of the topic at all, what you're saying isn't completely true.
The gambling industry is here for pure entertainment, and it should be advertised like that. Most MGA and UKGC licensed brands, as well as Swedish and Canadian ones, already abide by that. Some curacao or unlicensed brands aren't that attentive and I don't support that.
Additionally, most brands that are actually looking to make their name within the industry don't have any incentive into scamming you. Why would they scam you for $200 one time, while they could win you over and turn into a stable player who will continuously return to the brand? It just doesn't make sense.
However, the casino will punish your stupid mistakes, things like;
#1. You play from a restricted country with fake documents, deposit $100 and win $1000, but don't want to KYC. You will not be able to withdraw your initial deposit, or the winnings.
#2. Players try to scam the casino with several accounts open, either on that solo casino or within the casino group. Again, a simple KYC will solve everything.
#3. Players don't read the TOS and complain about wagering requirements, especially in money laundering cases.
I assure you that on every 5 casinos that are "scamming customers" there are 10.000 players who are scamming the casino. So obviously we build strong matrix systems to guard us from them.
I was also active within the scams category on this forum and I can tell you that out of 10 cases in 9 cases the casino was right. People just don't read the TOS or don't know how the industry works, they get burned and they end up in that section whining. The worst thing is you have to dig through it like an idiot, the last customer that "got scammed" was actually playing from a restricted country, but didn't want to tell us that, we just found it out through a random screenshot he provided.
