Yes, repost buster, i agree, and know that copyright infringement regarding the reposting of web porn is covered in the posting rules.
However, no matter how obvious that the pic is taken straight of the web, mods only have the right to delete webpics that contains an email address, URL or URL's in the pic, title or comments by the poster.
If the poster crops the pic to remove any watermark etc that shows the pic has been taken from another site then a mod has no right to remove it.
Read the rules mate, it's all there...
