I know /v/ loves hyperbolic outrage, so let me burst your bubble: the banner and other capsules can be seen specifically from direct links and API applications. They never (knowingly) approve certain imagery in these photos. Developers could and still can use explicit gameplay images and footage in the store page media. The games on the bottom of OP's image do not break these guidelines.

feel free to ignore my blogpost and continue talking about censorship to poison the well thank you
