Uploading things like music that is copyrighted is easy to get by if you know how to do it right. To start when you upload whatever your uploading you will usually get one of two messages the first will be Matched Third Party Content and the second will say Video Blocked in some countries. Now I am going to use music in this example and there are two ways to get by these blocks. The first is to go to the dispute form and click I want to file a dispute and then click the number 2 and paste this into the text field:
"Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use."
Now the second way is to use an audio editor, I use audacity and all you have to do is change the pitch by 5 and you usually will not get any of those messages and if you do use the method mentioned above with this method and then that should get the message to appear.
This works just fine for me. I have uploaded 100+ songs by artists like Lil Wayne and such and have got around those messages every single time by using these methods. If you have any questions feel free to ask but not in a pm cause this post could be helpful to other people.
