Thank you, those communities aren't very serious so I didn't even think of that. Users on the lemmygrad screenshot community do seem to be spending too much energy on something they dislike but that's up to them. Better they have a place to contain it. As for the other, I'm still not sure I really understand it, but it doesn't seem like anything worth hating an entire instance over.

ETA: those are communities hosted here though, that's nothing to do with our federation policies. I guess their silence speaks volumes here.
