If you want an instance that almost definitely won’t go under, sdf.org has existed since 1986 1987 and has an instance at lemmy.sdf.org

I exclusively browse “All” and block communities I don’t want to see. I haven’t found enough I want to sub to, and those I have subbed to don’t have enough content.

We need an option to block pornographic communities, but still see non-porn NSFW content. Blocking all NSFW is too broad and will block other content.
