I'm not sure if you are defederated with like everyone or just too lazy to scroll the comments before asking a question that's answered several times already
Lemmy.world is defederated from hexbear so they don't see the comments by Hexbear users here (which is most of them), but they probably are also the lazy type because they could just look it up if they can't find it in the thread, or view the post from another instance to see the missing comments.
