It looks like,asking from member who gave negative trust is only soultion in this situation.
Yeah. We didn't need to see another comment about it.
I cant understand why trust is out of mod's control till today.
To avoid centralization and allow it so that mods don't have complete and utter control. Single point of failure.
If there is no regulation on forum,how is that possible dark trust member can give negative trust to other forum member for the reason like untrustworthy behaviour?
I can't comprehend what you're trying to say here. There
is regulation on the forum and DT[1,2] members can give out impactful trust because it would (generally) prevent ignorant newbies from being scammed.
