personally i already pegged most of the people who have joined in the brigading as suspect a long time ago. and core's actions had already started to become suspicious 4 years ago.
there is professional public relations narrative controllers behind the curtain. all of the people who have piled in are bullies, and easy to give them a sense of safety in numbers and authoritative figures to defend their vicious behaviour.
i think that they are just coming out of the closet.
