went to tag some works with child characters as young for blacklisting purposes, noticed that some of them were already tagged as young_(lore). is this some new standard I'm unaware of? "young_(lore) -rating:s" doesn't seem to be caught by the global blacklist for logged-out viewers.

Lore tags are for stuff you can't see young_(lore) should give you characters that don't necessarily look young. The lore tags were introduced after the site update, some time ago, initially for gender tagging.

Edit: they are not good for blacklisting purpose. And they are not meant to be used interchangeably withe their normal equivalent. The normal tags still have to be applied according to TWYS

Since this site tags using the Tag What You See policy, the young tag does not apply if the character looks older (even if they weren't meant to be older), and does apply when a character looks young (regardless of whether or not they actually are). The lore tags, and thus young_(lore), do not follow TWYS, so it's used when a character doesn't look young but the artist or character owner says they are anyway.

As with lore tags in general, you shouldn't tag both the General and lore variant of a tag for the same character. A character that looks and is tagged young should not also be tagged young_(lore), just as a character that looks and is tagged male should not also be tagged male_(lore).

Young is for when the character looks young, regardless of actual canonical age.
Young_(lore) is for when the character looks older but is canonically considered young.

The two tags should be mutually exclusive, meaning that they should not be both tagged at the same time.
