Things like one instance banning another whole instance because that instance is not agreeing to the same moderation policies as the first.

I think some instances block all Pleroma instances, because there is an association of Pleroma being used by right wing folks.

Here are failed attempts to ban Pleroma instances outright:

Here's an example of an instance that blocks other instances if the other instance doesn't have a code of conduct similar to theirs:

https://mastodon.art/about

Note - they partially block mastodon.social!

>mastodon.art is a safe space instance

So don't join them if you don't want to be coddled. Anyone who does wants to engage with a different slice of the fediverse, and why do you care if they don't see you?

I'm not sure what this has to do with my comment or the one I was replying to.

fyi mastodon.social is by far the biggest (almost sole) source of spam, thus more and more servers are "limiting" it (as opposed to outright blocking/defederating) so people only see posts from users they explicitly follow from that server.
