you are like kids, guys
It makes funny to see that you do not want to think logically or you are a lazy freshman and want all be put into your hand with detailed explanations of how and where.... unbelievable
just go to myBet payment T&C for users or send a request to support, whatever.
As I know, the Maltese providers ask for IDs each time you withdraw more than 2k€
I'm not sure if it must be an accumulated amount or just once requested amount. Anyway, according to the Law, myBet must request those documents when you withdraw a big amount or, partially, up to a definite big amount.
so, myBet work clear as a clock, according to the laws.
by the way, I know few people behind the myBet and can assure you that nothing could go wrong with such managers. Their names are famous in the industry and they work hard to get it in the right direction.
good luck
