@r000t It looks like you've been here for about a year, but given this post it's pretty clear that you haven't really been paying attention. We've had instances that run whitelists instead of blacklists, admins communicating about problem instances, and problems with large instances since early 2017 at the latest. These aren't new fads. They're how the fediverse works.
I guess if your intention was to look out of touch and foolish, huzzah, you succeeded?
