ill give cliffnotes for those who cant see anything..
in the first example you see this image on yahoo
but the link is to
http://tourvideo.adult.com/trailers/1161hi.wmv
in the second example the video are all ripped from the shemp , but not one link is given to the site itself or even a proper domain format i.e. yoursite.com it just shows YOURSITE but doesnt specify .net or .com etc so they are using your trademarked names to promote videos from other sites ( basically recreating your entire mgp without any ads -for now - )
the third example is rather self explanatory , the video is from a diff site that archive.org has archived. so its an old copy of the video, so if your site was gone and removed and you changed domains , they will still have all your videos
