YouTube Problems?!

So i want to start a compiliation channel i was just wondering their are so many channels that upload videos without even having the right.
So i was wondering if those creator of those channels signed up for YouTUbe with their real information or if they created a fake account and just added their adsense account to it ?

I think a lot of people use fake names etc, but it doesn't matter, what will happen if you post copywrited videos is: you could get your video removed, but most likely the owner will just monetize the video from your account and leave it.

I was reading a lot of youtubes information about using content that isn't yours, they have something called fair use. These are youtube's guidlines:

• The four factors of fair use
  
  In the United States, fair use is determined by a judge, who analyzes how each of the four factors of fair use applies to a specific case.
  
  
  1. The purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes
  
  Courts typically focus on whether the use is “transformative.” That is, whether it adds new expression or meaning to the original, or whether it merely copies from the original. Commercial uses are less likely to be considered fair, though it’s possible to monetize a video and still take advantage of the fair use defense.
  
  
  2. The nature of the copyrighted work
  
  Using material from primarily factual works is more likely to be fair than using purely fictional works.
  
  
  3. The amount and substantiality of the portion used in relation to the copyrighted work as a whole
  
  Borrowing small bits of material from an original work is more likely to be considered fair use than borrowing large portions. However, even a small taking may weigh against fair use in some situations if it constitutes the “heart” of the work.
  
  
  4. The effect of the use upon the potential market for, or value of, the copyrighted work
  
  Uses that harm the copyright owner’s ability to profit from his or her original work are less likely to be fair uses. Courts have sometimes made an exception under this factor in cases involving parodies.
  

Good luck.
