Personally, I go by the, if I don't want to see it, I block it. And that has worked out very well for me. Mind you, I am kind of in a good position because I don't have any kind of like mental health things that make me absolutely not capable of seeing some type of thing before blocking it. Like I can see some crazy shit and be like you know what that's fucked up I'm blocking that because I've seen it once I don't want to see it again.
Edit: From what I understand, you can transfer your block list if you ever move accounts. So with me, if I ever left my instance, I could just transfer my list of blocked communities and subscribe to communities and be just as at home on another instance as I am here.
