pool #1784, "Shot out of canon".
While I'm all in favour of wordplay in titles, and the idea isn't necessarily pointless, the way it's described (and used) at the moment is. The stated description would include not only every use of the if_they_mated tag (and half the current contents are already from the Touhou Kids pool), but anything that's not explicitly supported by canon - that is, >99% of all fan works.
Yeah this pool seems much too broad to me. Non-canon images are incredibly common, and not really something I'd think to tag.
