Sure, but who invited a lot of those shitposters? Who set out the welcome mat for a certain type of individual? Who actively courted folks from the Chans FFS?
I dunno. I can say that I found the site independent of those examples you cited, mostly because of Yahtzee. And freely registered myself. Did someone send up the Douchebag Signal and summon the hordes of people to the forums for a place for them to spray bile? No clue, my personal experience was just that it was what I would consider the, perhaps slightly above average number of Internet Shitbags, that can be found pretty much anywhere, who were just REALLY dedicated to arguing with everyone.
Again, this is just my personal experience with the site back then, but I posted there multiple times a day, for several years around the Dark Times, and from my perspective, I remember people talking about shitty business practices, and how the site was dying, and the number of shitposters seemed to be a higher %, but I attributed that to people like myself, who were visiting less frequently, because of the toxicity. So I'm not sure if the site got flooded with them, or if it was just everyone else left the party, so it was nothing but a Shitbag Sausagefest at that point.
I will admit, that my involvement with the site, and most gaming related sites, is fairly limited to forums, and maybe a few content elements. I mostly don't care about things like developer discussions, or speculation articles about a game from 10 years ago, and how it impacted the sociopolitical whatever of some country where it was huge, or whatever. I don't really care that much. The older I get, the less I enjoy the culture of gaming. Which is somewhat depressing since I've been playing video games since the early 80s, and consider it my primary activity/pastime. But the level of toxicity associated with it, on every level that I've seen, the legions of fanboys that divide themselves into factions based around franchises or developer companies, going to war with each other over stupid shit like "which platform is better?" just, makes me tired. So tired, of all of it. So maybe I just didn't engage in the majority of the festering shitshow that was the old site. I know people in the forums talked about how terrible it was, in the nebulous rest of the site, but all the shit behavior I witnessed, was from their own forums, and themselves.
That's certainly why I stopped posting here for several years. Had nothing to do with Susan, or any others on the staff. The community is why I said "yeah, fuck it. I'm out."
