I believe it's vitally important that Fediverse/Mastodon instance admins see themselves as service providers instead of community moderators.
We are responsible for a user's social communication, not unlike email.
Our duty is to A) protect users from actual harm, danger, scams and Spam by using suspensions in this case, B) obviously not allow that our own server is being used to broadcast content we disagree with. C) Curate public timelines with silences only. They could be seen as a value-added service for discovery.
Other than that: paws off, let the users control their inbox.
I can't even imagine AOL defederating from GMAIL because an AOL user said something controversial.
Also moderation coordination between instances needs to allow for a reasonable time window as well as back and forth communication (ie. at least several days).
@Wander we're not at the scale of gmail and aol though, are we? and besides - most smaller instances block large instances like dot social because they have terrible moderation for their size, and we actively don't want everyone to flock to just a dozen large instances.
besides, who a user keeps as company reflects on them, it doesn't take much to conclude that someone whose entire friend circle is pepe-posting channer racists is more likely to behave in such a way themselves. I don't want users who'd want to get rid of the blocks we have here today, so the blocks keep them away.
