Even if they do rebranding still their past reputation will haunt them.
Instead of rebranding, it's better to restore their name on this forum by slowly resolving all existing cases that are directed at them, I think it's an easier way than rebranding, which will cost money and effort and also attract people's trust to play, even though cases can be resolved by them does not rule out the possibility that it can make everyone feel unsafe playing here. it would be hard to believe again.
I think all the campaigns that they have even the advertisements out there are not all successful even like a waste of time it doesn't produce anything because their site has a red flag that people in this forum know that it is a dangerous site and everyone should avoid it so as not to lose money .
Hard for them to restore their reputation since for many cases their casino involve maybe those cannot be erased easily. And I think attempt to do that but nothing happen that's the reason why they choose to run a campaign to see if there's still user would gonna play their casino despite of reputation they got.
But since their campaign didn't last long since no reputable people would risk to participate, then I guess they failed on that attempts to market their casino back in bitcointalk.
