Are pornographic pictures allowed?

hi, not everyone might agree with me but it is a disgusting picture, it is not art at all, it is pornography!there are sites in the internet for that first picture, You see there are children reading some of hubs here like anime topic etc,I sent this site the link of hubpages to my sons (aged 17, 14, 13) in the - Pain Vixens - Philippines, they read articles here at HP, what if they come accross that, other sites i tell them there to locked out but this site is not locked out, I appreciate sexy bodies, and all people are drawn to it but not that picture, the first is just pure porno
