The same thing applies. You can't decide that one thing is okay when others are not. Where is the line drawn? Photos, so no real pictures can be posted? Photoshopped photos, so nothing that's been edited can be posted? This thread has implications way beyond what any of the pictures actually show. Raul Moat and Joseph Fritzl are both real people who did horrible things too, but their photos keep making an appearance. I think Hitler probably tops the crimes against humanity league, but nobody shouts when his photo is posted. Likewise, swearing is not allowed on the forum, but apparently it's okay in the images. So you can't possibly start enforcing a rule that is incredibly hard (if not impossible) to police just because YOU happen to find this instance offensive.
