I don't think they are not thinking to come back since this is where they can possibly get a traffic so maybe they are waiting for people to get tired talk about there past scam and the try to launch a marketing campaign to test again if there's are people will try to play on their casino.
If you often visit crypto explorer sites such as Etherscan or blockchain.com and maybe on other crypto sites, maybe you will find their advertisements there, so they don't just get traffic from this forum before, even though this forum actually has a lot of crypto communities that can be found. to become their active users, but it seems that almost all users of this forum already know that 1xbit is a fraudulent site that should be avoided.
I'm sure they will probably come back at some point but not sure they will try to resolve their case on this forum and also hold a signature campaign, it seems like it will be difficult for them to regain the trust of all the users of this forum since they have already been flagged.
