Copyright laws and policies are tricky to say the least.
Believe it or not,Kat Von D was even sued over one of her tattoos.
Some of those most subjected to copyright challenges are YouTubers, though.

This is one reason why movie, television, and film reviews are so popular on YouTube.
They fall under the commentary and/or criticism pillars of fair use and are usually acceptable on YouTube’s platform.
Still, YouTube’s algorithm when it comes to copyright isn’t not the friend of YouTubers.

Does YouTube delete channels over copyright infringement?
Videos can also be manually flagged by people if their copyrighted material appears in a video.
This has been an issue for several years according toForbes, and the problem is only getting worse.
The problem has escalated the most within the music industry (viaThe Verge).
