I was trying to find the poorest VGChartz user, and I found an error here. If you go to this page: http://www.vgchartz.com/profiles/
In the top right, it says "Top VGChartz users". Press it, and you get a 404. This used to present all the richest to poorest users, so I guess this is a relatively new mess-up.
