Ah. Interesting. I sort of forgot about lemmygrad altogether. Guess that explains why.

I found a link to a list of who is defederated from whom on a “fediverse for beginners” post. I will see if I can find it again if you need, but it looks like some other commenters already got you covered.

I don’t understand this. I cant even name a single community native to the instance I use. I picked one that hadn’t defederated from anyone, and I block communities as needed. Also subscriptions are a thing.
