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 .
Rebranding, opening new spaces on social media and doing advertisement campaigns is actually cheaper than trying to go back to be an honest service which people can trust.
Also, I have got the impression their advertisement campaigns launched in the past have been targeted towards newbies and people who are not fully aware of the reputation they have, for example, you can check up their Reddit page and while the continued to advertise promos and contests there, they also blocked users from posting in their threads and deleted posts warning others about the selective scamming.
Even under a new brand, they will continue to do the same as usual.
