Have you used images, music or videos off the internet without checking if they’re okay to use under copyright laws? I’m sure most people have at some point, including myself growing up: download a small image for an assignment here, rip a song off YouTube there. It was too easy— but it could get you into trouble with whoever owns their copyright.
Most of us never have to worry about the consequences of copyright infringement. It’s not like most of us are posting self-made videos with Pokémon or Super Mario music on YouTube. If you are, Nintendo’s pretty notorious for hunting copyright infringers so maybe it’s time to rethink that “Me and Pikachu bae” music video you just posted.
(“Me and Pikachu bae” actually sounds like the cutest music video. I’d insert a sample of what that might look and sound like here, but it’d be an infringement and I may end up on Nintendo’s hitlist.)
