A YPP suspension demonetizes all videos on your channel, kicks you out of your YouTube network (if any) and prevents you from joining another network until the issue is fixed. Don't let this happen to your channel!
KYC is Know Your Channel, an educational video series by George Vanous, CEO and founder of Freedom!, that teaches you by example how to keep your channel safe and improve your content quality.
Lesson: Don't say "no copyright intended" as this channel does on their About page: "If you are an artist/record label and wish for your track to be removed please let us know by contacting the email above".
Get written permission for every piece of content you do not have the rights to upload on your channel.
