Yes, but unless those people have had their work copyrighted, he hasn't broken any laws.
I remember him being suspended before, but his account was restored. He does have a back-up account, but I still never have trusted YouTube's legal practices. I might sue them one day after I get out of law school.
But back on topic, the only thing I've seen him uploading lately was his B&W walkthroughs. So... I guess LPs are copyright infringement now?
