We must make a premise: there are different types of instances in the fediverse and some of these, especially mastodon, are of a strongly generalist nature, apolitical and dedicated to an audience that does not want to see disturbing content (Not Safe for Work NSFW).
These instances are forced to silence and sometimes block users who post content of this type without the content warning tag.
This can be considered excessive, but it is the only way to keep an environment free of disturbing elements such as overly fiery political speech, explicit content, foul language.
All this concerns above all the generalist instances.
As for the others, it becomes more rare to practice BAN and silencing.
Unfortunately, however, there are two types of drastic measures: those towards users of your own instance and those towards users of other instances.
In my opinion, the latter should undergo a periodic review, a sort of amnesty that occasionally cleans up the sentences imposed or at least reconsiders some users who at the beginning of their life in the fediverse behaved badly because they were used to the toxic environment of Facebook or of Twitter.
In fact, the problem with these users is that they risk being invisible for life from some instances.
