Fictional Fans

My journal is set No Age Restriction globally and I only rarely use the "Discretion advised" or "18+" flags, pretty much only on smut fic. I put ratings in fic headers or recs, but I don't also use standard tags for that purpose, nor do I use a general "NSFW" tag. I would put such things behind a cut, but then fic is generally long enough to merit a cut anyway.
