There's a girl who did her own investigative journalism and discovered that the "third party" that's responsible for banning products is ... Visa and Mastercard themselves. They created a company that they control with a directive to "protect their brand" by not allowing certain purchases. They then point to that company, which they themselves created and control, as the problem.

Interesting comment i found under the video about the situation

So Uzaki chan, who has breasts breasts bigger than her head, should be censored because it promotes people being attracted to undeveloped children.

But books like Gender Queer with actual dick sucking should be allowed in schools?

Now if it was actual hentai I'd understand, but shit like this never made sense to me.
