[Update: to make the game a little fairer, and to give appropriate credit, each picture is now a link back to Gelbooru; I hadn’t realized they let you link by the MD5 checksum, which I fortunately preserved as the filename. A quick bit of scripting, and I can also confirm that there’s only one tag (other than “1girl” and “solo”) that applies to all 22 images.]

In his cheesecake roundups from Gelbooru, Steven relied on an ever-expanding list of negative tags to exclude thing that definitely didn’t match his interests. The last version of the exclusion list was:

-1boy -multiple_boys -male_focus -penis -testicles -vore -rape -loli -fellatio -sex -bondage -furry -monochrome -amputee -anal -yaoi -abs -pregnant -shota -leash -tears -chained -noose -restrained -rope -asphyxiation -execution -hanging -corpse -blood -photo -peeing -gigantic_breasts -large_penis -huge_penis -futanari

I’d never really looked at the list before, and honestly, even after you exclude all of those, you still have to wade through a river of crap to find some decent pictures that match the positive tags you include.

See if you can guess what single positive tag I added to get the following pictures:
