Re: nutildah got red trust recent hours. Is the red trust fairly for him?
Like I said above, nutildah has a negative feedback based on DT (Default Trust). If you have a custom trust list, you may not see it in the same way.
Having trust score of 0: -0 / +1 really not possible. 
Why wouldn't it be? The "trust score" increases with time. A positive feedback (made today by Hhampuz) isn't going to score you any trust score. That's why the first digit is a 0.
