I see it all the time and it drives me nuts.
YouTube users upload movies, TV shows, music, and music videos that they didn’t create, and then in the description section below the video they write “no copyright infringement intended“.
Here’s the bad news: you’re still infringing on copyright by posting someone else’s work.
Simply posting that you didn’t intend to infringe on their copyright does not negate the fact that you are, in fact, infringing on their copyright. It’s not a legal loophole or workaround that you can use to post someone else’s content.
Here’s the exact scenario with a different thing other than a video: It’s basically like someone stealing from you and then saying they didn’t intend to steal from you.
I think you’d agree that they are still stealing from you whether or not they SAY that they didn’t intend to. It’s the exact same scenario: Someone who copyrights something owns that thing and has the right to distribute it however they want… no different than the money in your wallet. (I realize that copyrighted videos and money don’t feel like the same thing but they are. They’re both assets).
So, if you truly don’t intend to infringe on copyright then don’t post content that was created by someone else.
