Is mastodon.social defederated by a notable amount of other instances? - Lemmy.world

I’m currently on mastodon.social for my instance, and I was informed the other day that because of poor moderation it’s been permanently defedereated by enough instances to make it an issue for users there to have reach outside of their home instance. Is this true? Should I move to a different mastodon instance? Thank you!

I would also like to know more about instances being defederated and for what reason this might be happening.
Spam and bots like other people have said. Then there are the instances that get blocked because of the content and people there. Nazis, racists, trolls, etc. They were coming in from all over during the twitter migration. There was a blocklist on GitHub that was being updated pretty frequently.

In Lemmy, you can click on Instances (bottom right) to see a list of federated and defederated instances.

From my point of view (lemmy.click), mastodon.social is federated.

Interesting. Is there any instance which specifically will not defederate from any other?
This is what I want to know. I don’t want to be in a walled garden.
There is no instance that is connected to every other instance, and there never will be. Lets say your instance is a free speech instance that doesn't defederate any other instance. Even then, there are instances that will actively block your instance because they block all instances that are willing to federate with bigots in the name of free speech.
There are, but they tend to end up being quickly defederated themselves, because they attract bigots who want to share their bigotry without consequence
ahhh so this is why it seems like mastadon is less diverse than lemmy already!
