Given you are not slapping these UID's with Red Paint TM why exactly do you expect others to do it for you?
For 3 reasons:
99% of people don't cares about not DT trusted feedbacks
some managers do not cares about the trust at all, even the DT Red trust on their campaing so my feedback will be useless (we are talking about Bounty cheaters)
like in a trial, I Like the idea of accusation and judgment will be coming from different people (sorry for my English this verbal form is probably wrong).
Well...
I have one very valid reason you *should*give out your own negatives:
*IF* you were to ever find yourself on the DT *all* of your previous trust, good, bad and indifferent will suddenly be upgraded. Dozens or even hundreds of UID's would then automatically bump to red not just on your trust but every-ones.
