True. Most of their participants are spammers indeed which is expected since they don't mind negative trust thanks to advertising this scam site. However, spammers don't get banned in this forum unless they cross a certain limit.
Any idea about where this limit is, I am fairly new in this forum and since I joined I assumed things like spam and plagiarism were enforced quite fast, I got this idea from the appeal threads I saw on Meta.
Assuming what you are saying then I was wrong. Actually I did not even check if the guys I caught spamming got banned (at least temporally).
Bitcointalk cannot ban 1xbit or any other site for that matter. The best thing that you can do is file a scam accusation along with sufficient proof against them in this forum.
In theory, the administrators can but they have chosen not to, for the sake of freedom.
Even if he opened the accusation with proof, it would just be another scam accusation among hundreds of others against this casino.
Granted, not sure what the solution would be either.
