have we defederated from lemmygrad or is it the other way around?

I tried to interact with lemmygrad using this dbzer0 account but I can't. They also seem to refuse accepting my signup request. when I tried searching "lemmygrad" locally, I found relevant only this comment from captain @db0@lemmy.dbzer0.com appearing on the attached screenshot. I tried to follow the comment's post but it is not to be found. Just wanted to know the lore.
