Update (9/4): Just to clarify, if you take a look at look at his youtube discussion page then you would see his videos were remove two weeks ago, not just around one week ago and videos about Michael like Vegematic came around august 25 (8/25), so it's safe to say his video were deleted around the 4th week of august.
Update (9/10): well, he made a new video and it says in the description "Share this video with as many people as possible. It will be taken down."; the wield thing is that when go to his channel it says that you can "view 22 more" videos, but when you go to the video it just shows only his one video (the new video) and when go the page it says that he has four more videos, with the last thing begin that the comments are disabled.
