Mate there are several quotes from other users above in your post , they even explain what is other accounts in 1xbit had been suffering also and they received same response and that is the team stops collaborating in your account because of violating their rules.
I'm not sure what will come to you but one thing I'm sure that you will receive no response from the team as they have ended answering for months now.
It's pointless trying to advise some of these victims because they feel frustrated and desperately beg in order to try and retrieve their winnings. They stop doing this at some point after realising that they are wasting their time and move on.
Sad stuff, but this is what happens to many 1xbit victims which is messed up truthfully speaking.
