For me, the most important thing is about his seriousness to solve all the past on going accusations. Frankly speaking, I doubt 1xbit is really serious to solve all the issues but lets see and wait. If there is no good efforts from 1xbit, nothing will change here. Their reputation will remain the same, even if they can solve some issues.
About their reputation, DT member who give negative feedback will be easy to remove his negtrust and supporting them IF they are really solve their problem and accusation. See what happen with BestChange, he get lot of negtrus before and now turns to positive. same with 1xBit.com if they are really solve the problem, everything will be fine. But, if the proof not enough their reputation will be Always Bad.
