I agree with you. I have a feeling they had a code to update the list each week, but that either something happened to the code, or they just never updated it or something. I do know that it worked for a while. Most of the time I've beaten the world high scores and could do it every time if I didn't just get the score needed and quit.
I've never seen my name on the list, or anyone I know (from the group).
I think they gave up on that part of the site, or just don't bother to fix it. But I agree, I think they are fake names.
