Yes, I remember at that time I did KYC and got a bonus to play. Stake has enforced it and it is something that must be obeyed by users. At first we could play without doing KYC, but after the rules were enforced we couldn't anymore.
Logically it is impossible, and maybe the person who said that most likely has a personal interest and maybe they intend to cheat. Especially if they say jockey and so on, that is very suspicious.
It's REAL you can find it easily in local groups related to gambling, I know you are also a local user. Accounts created before KYC was implemented still get bonus offers even though they are Non VIP and Non KYC, this offer is still active since February until this month and the bonus amount varies, maybe Stake has certain criteria. If you are wondering why Stake does this, the answer is obvious they want to remind old users that they have a Stake account and get them active again meaning Stake doesn't want them go to another casino. By the way I have some connections with old gamblers in crypto casinos, in local if you understand what is ''jack site'' then you are one of them, I also have friends as Mod in the casino.
