Correct,
Even if if 1xbit is able to resolve all the issues, it does not mean that they will get good reputation instantly after resolving all the issues. It will take years for them to prove that they are completely changed to be a better site with no serious accusations. Although there is saying "no late to be better", but 1xbit waited too long time before they try to resolve all the issues. If they could do it earlier when there was the first scam accusation, I think their reputation wont be as bad as now.
Too late for them since most of people that have experience problem in their gambling site is not all is still active today. They should resolve that issue that year when there are many accusation throw to them.
One reason that I think why they want to resolve it today because they want to back their business and be live again . But we as users that experience problem before are also afraid that something much worse will happen if they really return and trust again by users.
We don't need to wait for that because if they really concern with their reputations, I am sure they will solve the issue one by one, and they will try to serve people better than before.
They have a bad experience before, so they need to manage their site seriously, and they must eliminate the things that might be a problem for them in the future.
It really needs hard work to recover their reputations, and as @Bitinity said, it would need a long time to convince people to come back to their site because people already get a bad experience.
This time, they need to explain the issue's details and don't make the customer have bad memories of them in the future.
The customer is the king in the market.
