So a shitty Twitter thing I sure as hell don't miss is that I don't have to deal with being blocked by hundreds/thousands of people I've never interacted with just because I'm friends with somebody a few popular people hate.
And I love how when we DO have mass blocklists with the instance blocklists, it's actually about shitty behavior and instead of personal beefs.
There's obviously a couple known instances that ban any vaguely leftist instance. And that's shitty, but that's a different kind of shitty. And seemingly the exception and not the rule.
