First, Technical Support isn't the right board for this kind of issues (this belongs to meta).

Secondly, AbBitNut isn't even in the DT2/DT1 list so there's no way that "that" old trust rating will show by default.
Next, Trust isn't moderated: Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ means that moderators will not meddle with trust issues (with some exceptions).
Lastly, check your Trust Settings if you've manually included him in your trust list or you might have selected Trust depth 3-4 and he's on that list.
If you did, set it back to default = 2.
