There was an issue a while back where one of Microsofts staff created a little WAV file with some cracked sound editing software... This didnt effect any users of Windows (in which all XP or 2000 had this WAV file on) but I am sure the sound creator at MS got a good beating
I believe the same would apply with website design. It would be too hard to police and have legal teams recall every image and site designed and go through legal processes with every owner of a site.
