Beehaw is blocking lemmygrad, they're federated with lemmy.ml which is federated with lemmygrad, though.
I'm a member of the lemmygrad instance and I don't think I've see any content from beehaw, so you should be good over there.
Edit: Okay, I can confirm you cannot see any content from users in a blocked instance. I just looked at this thread from slrpnk.net and you cannot see my comment. And I also just read that you didn't want to join beehaw. What's wrong with beehaw?
