Right now, the wiki page for hairy_balls says not only hairy balls (as in humanoid pubic hair) should be tagged with that tag, but balls with fur should be tagged with it too.
I feel that's unfortunate, as pubic hair and fur are different. I like both, but I'd expect hairy_balls to usually be on humans and not on anthros.
However, the pre-existing tags furry_balls, fuzzy_balls, and fluffy_balls have unclear boundaries. Should two of those be aliased to one of those? Or should they stay separate but with more clear usages mentioned on their wiki pages?
