“Starting sometime in 2017 through to at least April 30, 2021, Fernandez and Teran began monetizing music on YouTube for a vast library of more than 50,000 songs, none of which they owned the rights to.”
Two men claimed 50,000 songs they didn’t own and pulled $20 million out of Content ID. Some of the paperwork was forged. It ran for four years. YouTube built Content ID to take money from uploaders on a claim alone. It never checked who was doing the claiming.
