The video says as much. His account is locked until he agrees that he violated terms and deletes his post. Since he won't do that (because he would rather die - which is wayyyyy too dramatic for this issue) he is effectively banned, even if his account still exists.
I am someone who thinks pronoun changes are idiotic (Ezra Miller, you moron), not some snowflake or leftist who loves this weird shift in our culture. With that being said, while I normally agree with Jordan Peterson there were several things in this video where I feel he is going off the deep end. It was pretty cringe.
