I believe, that because some users play with large amounts of money in online casinos, it would be for the best for all of those users to be warned that using VPNs "might put them in more problemetic situations" when asked for their documents/I.D. Anyone who probably has played in casinos regularly, OR has tried day trading in different centralized exchanges, has always experienced KYC. More than 90% of them probably has not alarmed that casino/exchanges, but why do some of them make a brand new account, and complain more loudly than usual in the forum?
