the thing everyone has to remember about a harassment campaign is that once its all said and done and successful everyone gets to wash their hands of it and act like it never happened and if it did they certainly weren't part of it and if they had any confirmed involvement its actually they who were the victim of the campaign because they (allegedly) get threats about it on occasion./s
dropping the sarcasm even ignoring a certain duo being like, spearheads for it 5 years ago, I think you'd have an easier time coming up with a list of everyone who was active in the fandom at the time who didn't participate in harassing the old hiveswap and homestuck^2 teams. guarantee it is a list of like less than 50 people (as an optimistic guess)
