That's what made me rather curious and asked him, because I consulted to his post history and seeing the amount of scam accusations he raised, I believe there is a significant chance that he got banned by one provider, and this is the "after effect" of that initial ban.

This is not the reason 100%. btw, I started with cryptobookies not too much time ago, and i'm opening 1 daily, and just 1 out of 10 try to steal me. All the rest pay perfectly. And most of them are Bety clones.
