I mean - I'm not a coder or anything even close to it, I can use systems but I got nuthin on how they're built - I would think that you could put together curated lists of The Big Tropes, even. Made Them Do It, Aphrodisiac Substances, Body Modification, ect. ect. Right? TV Tropes does this, and it seems like their linking/search/browse system works pretty well.

Obvs. there would be ~stuff~ about how they were designated/phrased/what was left out, which is why I can see utility in SOME uncurated capacity, but as a writer I don't feel like categorizing a "magic made them do it" under a broader "external coercion" tag, or something like that, and then using freeforms for greater specificity, would throw me too far off.
