It does seem to me that Not Yuri (doujin tag) means "not yuri (because it involves non-girls)", whereas Not Yuri (image tag) means "not yuri (because they're claiming to be straight)". Interesting.
You'd think the Product placement tag was for the Gunpla, but it's actually for the Switch controllers. Hardcore retro gaming in AS 122... or maybe Nintendo just never comes out with a Switch 2.
Sometime, if I'm really bored, I should go through this tag/Lots of/Insane Amounts of Sex and tabulate how much sex the average work in each tag actually has, in terms of total and relative pages and panels dedicated to it.
