I feel like this is abit of a sensitive subject but I'm still curios if this site aloud that?

I've seen various fanart that the original person has deleted but it still exist in other sites, would it be aloud to post some in here?

By The Way: I'm not talking about the kind you'd see in DeviantArt, I'm talking about ones you'd see in Pixiv.

i imagine its fine since some (not all) of Ogino Jun's Gamma images are posted here.
