Not that I know of, but it should be added in for those who don’t want to interact with people from Hexbear. If people have the freedom to block an instance for themselves, it would expand the decentralization that Lemmy is built on, since people don’t have to move to those instances to block out Hexbear.

I’ve read that blocking the Hexbear domain is a solution to this, but that isn’t a proper solution, since those who aren’t tech-literate would have a pretty hard time doing that, so a first-party solution would be the best.
