Implicating tit → bird
Link to implication

Reason:

So that people stop trying to put tags like "tit", "booby", "chesticle" on pictures

Aliasing to invalid tag or disambiguating it is a better idea.

Or maybe alias to breasts instead?

when in doubt

disambiguate

Alias to tit_(bird)

It's not commonly tagged anyways, and the mistags are easy enough to spot.

I've made the following changes:

• Implication: tit -> bird (denied)
• Alias: tit -> tit_(bird) (approved)
• Implication: tit_(bird) -> bird (approved)
