The main reason behind this happening is after the Merit system was introduced and this type of users are given DT status who thinks that they have all rights to punish anyone who they think are or will or become scammers. They way he talks are clear arrogant and dont bother about the forum reputation, he only just go by his own way whether it hurts the forum respect or not.
I think Theymos should consider about this type of Issues so that the forum should not get the valued users moving away from Bitcointalk forum.
