He probably didn't want to get his normal account red tagged because as we all know, it usually happens when you try to attack DT1 or highly trusted members. That being said, some of the yahoo's old posts seem quite worrying to me. It is definitely hypocritical to tag sold accounts when he was selling and also trying to build up reputation. Then again, I doubt anything bad will happen to him with the info you provided.
His "normal" account is already red-tagged the wazoo, so no, this is just the opposite - trying to make it look like more users are joining Quicksy's vendettas.
The whole idea that
if you tag someone for something then you have to tag everyone who's done the same thing is one big fallacy. Despite Blazed owning 12% of DT or whatever, the remaining 88% could easily tag those users if they choose to do so. So again, Quicksy is just throwing a fit like a 3-year old who didn't get his ice cream for breakfast.
