Never heard of this site before to be honest. Weird thing is that the gambling sites whose names start with lucky usually end up as scams and Luckyfish seems to be a scammy site too based on what some posters above posted.
Coming to the issue itself, chat bans happen for a plethora of reasons(fair and unfair) in all kinds of sites which is why the issue you brought up is pretty common and trivial and easy to resolve op.
