Yeah honestly it's not that serious for me. Personally I've never even visited the front page of 4chan. It's a word that's been around since long before social media too, as far as I know. One other place I've seen it used is autism communities when someone is describing their feelings about fitting in, or not.
I feel like 4chan is a US-centric thing. And a niche one at that. So it's a very niche US-centric thing to assume about random strangers on the world wide web. For a word that a lot of people probably use differently.
Yeah that's been one of the funniest parts to watch. It's been moderators versus admins but not users versus admins. Personally I think it's a pretty simple concept that the instance rules come first, then the community rules. I'm not surprised by anything I'm seeing or hearing on the admin side because I think it's pretty clear what to expect when you enter the place and read the sidebar.
