I agree, it's definitely not something anyone that claims to be a professional should do.
Whether or not either of you are trolls, I don't know for sure. But I can say that Greg's own behavior, by making this post calling for a flagging brigade, speaks volumes about him.
He agreed to have an open discussion with me here today and personally I think it was just a case of Greg letting his emotions get the best of him. Similar to TraderGlen's quick trigger reaction. I actually care about credibility so I would never go off like that...but I understand why he did it.
