An interesting article has been posted about an interesting case of piracy where somebody has been reposting content on Youtube with added advertisements.
"All you have to do is visit YouTube, find a top rated video. Snag it. Open it with some consumer video editing software like iMovie, Final Cut Pro, Video Vegas, etc. Add your advertisement(s) and upload the finished product to YouTube with the same tags and title. If it was popular before you added your ad, it will be popular again. You get all of those gross impressions free!"


So i can see this technique of "spam" will most likely be appearing alot more on video uploading websites etc.
