What's worse, or maybe not worse but more detrimental, is that you can't see chains of comments on replies to a lemmygrad user. I have this account on lemmy.ml and there was a thread about the UI that I commented in from my lemmy.ml account where I replied to another lemmy.ml user, who had replied to a lemmygrad user. Looking at that post on sopuli.xyz and beehaw.org both my comment and the other lemmy.ml user's comment were not visible on sopuli or beehaw because they were nested comments to the lemmygrad user.
It's really bad for lemmy that individual users don't have the ability to block instances so that these instances could federate with lemmygrad again.
