I'd like to say that those scammers do their practices this way because they are virtually untouched this way.
Online casinos are like an ordinary private company; decent casinos purchase licenses to be recognized as fair companies. However, there is no online policy for guiding business practices, I'm afraid.
Besides, no one monitors your Telegram channels to alert you before you click on the scam offer.
There is basically nothing to with that, since the company is not licensed, owner is disclosed and players keep registering. 🙁
I'm not saying it's anyone's fault; if you think about that, this is precisely how scamming works. Bad intentions are always impossible to root out.
