I dont trade ever. This is principle.
Let's not focus on extremes that to me bend the trust system out of any use. I mean if i saw lots of ppl with red trust for lemons then I would disregard the rating altogether Im sure most would too.

I will have him explain in full the reason so I can demonstrate there is altenative motive here. If he come with something valid that I can not fully rebut then let's see.

If he fails to produce a valid reason then he must be removed as a start to making the trust system a sensible rating indicative of how much you can trust someone or how truly undesirable someone should be view for presenting facts and stats.

You can not try to use it as a bully tactic to silence people who analyse stats and cause others to analyse futher.

You can not try to concoct a fantastically improbable story to give red trust to someone when their is clear other motive for doing it. That is dishonest and not part of a trust system.
