I was mainly thinking of this because I will run across anime LDs and see that they are also p0rn. If multi-category is impossible or opens up a can of worms that you would rather not, perhaps a hentai category?

I was thinking exaclty the same ! I wanted to post about it :
"adult" category is maybe too large.
We should have "pornography", "erotic", and "hentai" categories.
I sometimes mind about actual "adult" category, because, I hate pornography as much as I love erotism. Then I wouldn't like to watch a p0rn movie instead an erotic one... !

I didn’t even know LDDB had categories. I usually consider them useless.

Actually it has "Pornography" and "Adult" for softer categories.

I use these 2 to hide covers from search engines and non-logged users to comply with child protection legislation and avoid Google block LDDb.com from their index. Also use "music video" or "live concert" to generate the Music index:

Also to link the Opera time table:

The field is set to a single value... could be multiple but then we'd might start IMDb wars when people disagree on what genres a specific movie is.

Let's keep it useless maybe for now?
