My artworks were stolen

Feardog, a popular YouTube Lofi channel, stole my artworks and monetized them without my permission. I filed copyright strikes against those videos to have them removed but he decided to threatened legal actions, countered my copyright claims and claimed that he has rights over the artworks that I have painstakingly drawn over the course of a few years. He did not spend any time drawing any of artworks yet he claims to have rights over my artworks and earned money from them. I am not given any compensation for any of the loss profits and yet he continues to thrive stealing people's artwork. I have provided more details on my Instagram page! Please help me share and tell others to avoid this unethical channel that has decided to steal and profit.
