It's not the first time some players have tried to exploit 1xbit's software and cheat on it. Otherwise I don't see the point in buying an account that has lost a lot. Mysterious things are going on here. When will cheaters finally gamble fairly? In this way, it is not strange that 1xbit closes accounts if there is cheating. I also think it's quite normal for every bookmaker to intervene against this.
I think for a while the cheaters had a way of avoiding being detected by 1xBit security. When 1xBit improved security, it started to detect them faster and block accounts. This infuriated them and they are now taking their revenge.
