About those deleted vids...

I seemed to have noticed that two different things have happened with these missing vids. Some have stayed on my profile but have that big "DELETED" sign on them. Which is usually what happens when a particular user retires his profile. And it does seem like a lot of those vids may have been from one user.

However, there are other vids that are just COMPLETELY gone. I mean, they don't even say deleted, they have just vanished from my profile altogether. As if they never existed.

Has anyone else noticed this too?
