Defederation should happen after an instance has created a problem, so the community can actually have an opinion to voice that isn't based on speculation.

I know we aren't talking law here, but still, there needs to be a crime before we can have a trial. There needs to be evidence of wrong doing and harm created.

This preemptive judging does not inspire confidence in Lemmy as a whole. There has to be a standard, and I don't believe admins pre-judging instances before anything has even happened is healthy going forward. This is an extreme slippery slope and the more normalized it gets, the faster the ideal of fediverse dies.
