The title says it all. I understand if one or two of my videos are stolen. That's still okay. But these weeks my videos are being stolen en masse. Not only stolen and re-uploaded, some videos are renamed so that if people are searching for my videos the top results are NOT my videos. But lately someone did this to me : For example, I have 5 unique, high quality videos. These videos are clearly mine, complete with my company's logo on the sides. Let's say that their title is A, B, C, D, E. The thief downloaded all of them. The thief renamed video B, C, D, E into A. So, if people are searching for video A, the results will A, B, C, D, E, although the content of the video itself is not changed. So, the video B have the content of B but the title is A. The thief uploaded my video to their own channel. 100% of the thief's channel is my content, stolen from my channel. The thief have 3-4 channels. The copycat videos didn't have much viewers, roughly only 1-10% of the original videos. No comments, social signals, and that kind of thing. The original videos sometimes get comments, likes, and dislikes. The copycat videos have AdSense enabled. In practice, for every video I have they got 20-30 renamed videos, so the real video, which is uploaded by me, usually drops to page #2 of YouTube search. The description of the video is changed. The copycat version have stuffed keywords in it, complete with LSI and secondary keywords. For example, if the video title is "The Failure of Asian Market" the copycat version's description is : failure asian market, the failure of asian market hd, failure of asian market 2013, failure of asian market now, etc. While the original is merely giving the excerpts of the content of the video. I have reported the videos to YouTube, and still awaiting their response for my request of DMCA takedown. I believe this is not a manual job, because of the change in the description, and the speed of the work. I believe that this is some targeted attack, because all thief's channels only have MY content. My questions : What is the purpose of doing this? If the thief are looking for money, it don't work. Because although they have Adsense enabled most of them only got very low amount of viewers. Can my competitor do this to me? How to mitigate this kind of problem? Thanks a lot, BHW!
