Problem here is, the people they tag for being shitposters are not competition for the high paying hero slots that the new dt member's are after. They usually tag senior and below members and users that have spammy posts which would have never made it in the campaigns anyways.
Actually I have been given red trust (I never join signatures campaign tho, this was an exception).
You may be competition in unmanaged campaigns to other shitposters, but not to the user that gave you the rating.
