My guess is that OP's main account is already tagged by DT and he therefore doesn't have much to lose by posting with it. I think he just wants to play the victim, having to create a new account so that those evil DT members won't give him a neg *such injustice! much victim!*.
Don't be fooled by the illusion of all these noob accounts who seem to be supporting the anti-DT trolling campaign. Expect to see more of them emerge. You can count on that. Cryptohunter et al see that they're not getting any genuine support for their arguments, so they have to knit some socks. It's transparent, and it would be laughable if it weren't so insulting that they think the community is stupid enough to fall for it.
I respect your thoughts as most of the time they are satisfactory and straight forward, also I am not being fooled in anyway by the DT- trolling happening lately in meta and other parts of the forum. I would rather give a personal opinion which I think has a sense of Justice in it.
Firstly we don't have specific rules for neg-tag which is a very big problem for now as most of the negative feedbacks are posted with not enough proof or not under any universal value. This not only makes DT look harassing and monopolized to others but also makes people think that it's just a group of people imposing rules for profitable gains or power. But if a forum endorsed set of rules for tagging would be applied here it would just put a stop to the troll as no one would directly oppose the administration as its there show already.
This case too refers to the same thing as there is no base for the neg-tag. OP thinks its a abuse of trust system and the person who tagged thinks he is right at his own set of rules to tag which he has in mind.
