I don't particularly agree with leaving negative trust over this, but I can see the argument that someone willing to promote a (partial) scam for personal benefit is a high risk person to trade with.
So sportsbet is not a partial scam? Make a decision and act like a responsible DT if you truly care for the community. The one tagging the participants, wants out of the DT so his judgment is questionable as a DT, time to distrust him so this abuse will not happen again. I like to relate this to some members saying about livecoin should be tag even at one scam accusation to prevent future damage, this DT is starting to do damage of the account he tagged.
Reminding you again that a scam accusation is not a scam, if Livecoin is a scam, authority had already ceased them.
