I don't remember ever seeing quite 16 videos as the first results.
But I do know that YouTube has become a spam farm because it is so easy to rank via YouTube: choose a target keyword, create a video with a couple of frames featuring an enticing image and include a link to whatever malware-infested site you want in the video description.
Rinse and repeat. I wonder how many have become very wealthy using this technique.
