) Sure, but that becomes impossible when you have 100 different pokemon birds for example. The same logic applies to the opposite you know, if you did not wanna see charmeleon while searching for dragon, you could -charmeleon. Hey look at that! Or if you dont wanna see pokemon at all, -pokemon, hey look at that!
In this case though, it vastly improves usability because you cant search tags that are not there. If a few things get overtagged that is less of an issue than undertagging, because undertagged stuff has no visibility.
If I upload an image with 3 tags, then it will essentialy never get seen, even if it would fall under other people's queries if tagged properly. If I upload an image and overtag it, it may show up where it doesnt belong, until someone comes along and removes the reptile tag from my humanized snivy.
You are repeatedly being hypocritical regarding this whole thing. Pokemon are not a special fucking case within this whole deal.
Even your own site underlings who agreed with you in the past think you're being hypocritcal here.
