I appreciate your decision, although sometimes I would not agree with QS but as you mentioned, he is intelligent. As a human there would be mistakes (small or big), likely no one out of that. But if someone hardly try to change their behaviour then they would deserve second chances. There is still so many negative feedback's on QS profile, not sure if they reconsider it. I know everyone's judgements wouldn't same. However at least we can say that it has begun to implement theymos's thoughts.
Out of that topic, OP will you reconsider to visit
jeremypwr feedback? I know he was involved with ponzi previously and that's why he got multiple negative feedback's. But lately he is doing well and out of such as ponzi schemes. Have noticed some DT's already reconsider with neutral feedback. Although I don't have personal relations with him but had worked with him long time on his campaign and he proved that he changed himself (IMO). So suddenly came on mind and expressed it. Hope you will revisit his profile.
