well at least we can watch them on cinemassacre :c
Yes, but that means that there are no longer people in YouTube who
A) Produce quality entertainment
B) Are original
C) Put loads of effort into their videos
And
D) Have been in YouTube since the beginning
EDIT:
maybe they didn't get permission to show videos with licensed things? idk 
he was a partner right? don't you need to have a special thing enabled to do that?
The latest video they have on Cinemassacre is "Name that tune - Metallica". Maybe they tried to upload it and got copyright infringement related issues with it? The Cinemassace channel is also down.
EDIT2: The channel "Jamesmoviereviews" seems to be down too, i suspected that this one wasn't a viral one but hey whatever. I still can't find it anymore.
