Yes. If you're ever banned for posting an image it'll say "age of participants" the key word is "participant".
Participant in what? Sex? Is the character in a sexual situation? If not then challenge it. You're not going to get banned for posting a Cupid Statue pissing in a fountain. Even if you're a pedo with a water sports fetish - that's only your subjective experience. It's not objectively pornographic. These nude goku screenshots are regularly posted on /a/, which is a blue board.
Participation is encouraged after all, and they're not going to bend a knee for spectators who abuse the report function to enforce their personal entertainment standards.
Like, 1 person dumps 100 images. Maybe there's a furry in one and it get's reported. Will the mod delete it? Who's objecting? Op is the only one participating in the topic! Why should a spectator have any say in things? Who'd really damaging the boards integrity? The poster that's stimulating activity? Or the reporter that would inhibit it once the poster is gone?
