This really only works in a low volume situation. There's about 500,000 hours of video uploaded to Youtube every day, so employees would only be able to actually watch an insignificant fraction of that per day. Additionally, they're unlikely qualified to judge whether a video is actually good or bad. They can judge the sound quality, or videography, but unless you're well versed in the field the video is about, it's pretty much impossible to determine if a video is actually offering novel or good information. Additionally, the bots upvoting content are going to have several thousands, possibly hundreds of thousands of bots. So detecting the circle is going to be very difficult. Even more so if you consider a lot of legitimate users will have the same taste and watch a lot of the same videos.
