No ratings at all. No entry ratings, no basic access rating. If I post a fic, I'll put a rating in the entry for it, or I'll put a slight content warning in a cut-tag if it's a sensitive topic post, but that's as far as I go.

I don't even notice when people have put ratings on their journals/entries. I just skim right over the little icon. Only notice if I got logged out somehow and my reading page suddenly has weird cut tags on it.
