Rape is a bit more black/white on usage, other tags can have a slippery slope. Even rape, though, if you’re talking sexual assault rather than sex, I could somebody thinking the rape doesn’t apply, especially if they think it’d scare readers unnecessarily (ie, for blood play, they’ve got blood, they’ve got sex, but the blood’s incidental, not really part of the sexual acts).. As to my method, if I’m unsure or the tag is background noise, I’ll list it along with a short annotation why it may apply (ie, Minor1 because kids are running around naked, but there’s no sex) – guess that means I’m tagging the tags?
