As I was looking through my favorites list on YouTube, I come to notice I had a ton of deleted videos, some dating back as far as 2007, then come to find out it looks like JohnnyL80, who was perhaps one of the biggest preservationists when it came to vintage closing logos and logo history compilations, had his whole channel completely nuked.
But, I see where he's already opened a new channel, and appears to be in the process of reuploading his old videos . . . that's probably going to take a long while.
