Also, I want to clear something up about silencing an instance. When instance A silences instance B, that doesn't stop all content from instance B from appearing on instance A, and it doesn't get rid of existing follow relationships or prevent new ones. Here's what it does do:
Users on instance B may not send communication to users on instance A without those users' active consent.
That's it. Users on B aren't cut off from users on A; they just need consent to communicate. That's all.
@tcql It's the first rule of the internet: in the absence of information, assume whatever it would take to drive you into a blinding rage.
