@one_old_coder@piefed.social As you are on lemmy.today, which federates with fedinsfw.app (lemmy.today/instances), you should be able to subscribe to (join) communities on fedinsfw, e.g. lemmy.today/c/fedinsfw@fedinsfw.app .
Maybe you need to unblock visibility of posts flagged as nsfw to see any content in the spicy communities.
