I'll quote this one as it summarizes the latest exchanges of communication. Has someone suffered a damage or financial lost caused by the user you mentioned? Or, does the user you mentioned poses a risk of causing other user financial damage?
Do you think fraud is only about money? I have provided evidence of cheating. Are you defending someone who deliberately wanted to cheat the community?
They're [arguably] abusing merit, I'll take your word for that and won't bother to crosscheck, but do they cheat the community that warrant a negative feedback? You requested us, the DTs, why doesn't we leave them a negative feedback. And you've been repetitively asked, "what scam?"
Perhaps I should invite you to reacquaint yourself with what trust feedback said and dictate,
Do the users you mentioned poses a high-risk to the community if they trade with them? If you can provide arguments backed with evidences that they poses such threat --thus will potentially scam the community-- I'll probably consider about leaving tag. Otherwise, it's a case of merit abuse, not a scam.
