pool #4639 - Touhou - Youkai Extermination Sanae
Way to take it too far.
Yokai extermination was one of Sanae's reasons for being a playable character in UFO. This led to a rash of images of her being evil or crazy and to a meme of her bullying Kogasa. All in contrast to the previous "good girl" meme.
While the pool needs a little cleanup (and more examples), many of the images that have text explicitly referring to youkai extermination, and it serves as a way of unifying a theme that is quite hard to tag as you've demonstrated. Oppose deletion.
It's ridiculous how every touhou character gets their own pool lately. (Aya even has 2, Yukari has 3)
Edit: Kyubey has 4 whole pools
Not a cause for concern, IMHO. Touhou makes up approximately 20-25% of the images on this site. It's got a fandom that spawns many memes, and keeping track of them is useful, especially when tags don't cut it.
Kyubey is just a memetic machine and earns his pools, IMHO.
Reminder (pools mentioned earlier that are still here for some reason):
pool #4169 - Touhou - The Yakumo Family
pool #4440 - Touhou - The Moriya Family
Support if and only if an effort is made to go through those pools and add appropriate images into Family Bonding, pool #2140.
pool #2459 - Panty & Stocking - In-Style Erotica
3 tag search. Not good for mortal users. Oppose deletion.
pool #4347 - Ears off!
Support deletion, but I'd like to see a tag replace it.
pool #4025 - Masturbating at the Computer
Weakly oppose. You could do a few overlapping 2-tag searches as a mere mortal user, but I think it unifies a theme pretty well, and it's not hard to tell what should or shouldn't go in it. I'd support it if computer_keyboard & computer_mouse both implicate computer.
I support deletion of the rest.
