If there was just an accidental flaw in the provably fair, and you fixed it -- it would be no deal. But there is a large amount of evidence that not only is your provably fair flaw, you were also actively cheating people.  Unless you can somehow managed to provide convincing evidence that you were not in fact previously scamming people with rigged games (or provide a realistic explanation to why it won't happen again, like: our co-founder thought it was a good idea to rig games but we have since fired him) , I see no reason to remove my negative trust. A fixed provably fair system will just allow people to properly verify games, but it still won't prevent you cheating.
