The youtube users who create a channel, then rip everyone else's videos, to make up their own "car crash compilation", or "best motorbike accident" videos, etc! This is illegal ripping to start (stealing other peoples artistic content). Also they are creating these videos for the views plus ultimately to monetarize (requiring no real effort on their part).
That's why it can be a good practice to add a permanent "stamp" in the corner of your videos - making it much less desirable to them (as you then have blatant evidence they ripped your video).
