I think lots of instances, basically any of the ones that haven’t been defederated. You could also apply directly to beehaw.
lemmy.ml is still in with them, that’s probably the biggest. Kbin also works I think. Basically just pick one out of the list of instances at the bottom of any webpage.
I do have a beehaw account, but I had moved away from it because I didn’t like that I couldn’t make communities with it.
It’s just frustrating that one of the instances with the most content is fracturing away from others.
Who knows who they’ll defederate next and it’s obnoxious to try to keep up with it.
I wish I could at least still see the content. Not being able to interact with it I get, buy not being able to look at it is frustrating as hell.
