The chances of the 1xbit scammers drawing a line under and then turning a page and putting all their shady, underhanded and illegal activities in past - is unlikely to happen as that would mean they would have to own up to their past scams.
Just imagine though for a moment, if they came out here and apologised to the community and apologised to all their victims then made them whole again by returning the stolen funds and after all that were a transparent scam-free business, it would be a great achievement but as you correctly stated it is not going to happen.
I don't think there is any way 1xbit can salvage their reputation. It is way beyond salvation now.
Of course they can. All they need to do is work with the community and address all accusations that have accumulated against them, show evidence if the players violated their terms of service, and stop further scamming... But we already know that will never happen.
