I guess that explicit gay pictures are not allowed on this site, but pictures of underage characters are huh? Just listing the hypocrisy here.

It's just 1 down vote, we are not 5 users (who can do up/down vote), but we cannot control or force to up voting each image that we don't like, or it's out of our likings.

PD: Your argument is pretty valid, but to certain context. Example: This image is deleted because an absurd reason, out of Danbooru ToS.
