is digg.com rigged?

Have you ever noticed that the same people keep getting the highest diggs?

Have you wondered why? or how they always do? have you wondered why your submissions never even get noticed? I know that I have. On a few occasions I have submitted stuff beforeanyone else and only got like one digg, then flamed to hell and noticed that someone else submitted the same story after me and pulled well over 1000 diggs. Why is that? Do you do follow up later to see what is going on?

See I go to the photos sections.

And, well, I notice something. That only certain people get butt loads of diggs. Is it that people will only digg something from someone if they see they already have a bunch of diggs? is it that people will only digg something if they know that everyone else already thinks it is cool? I mean is that what it takes to be cooler? is to be cool already?

I just wonder if this is a simple advertisement scam. I mean not all of it has to be a direct advertisement, but I would bet that more than 90% are in some shape or form, just a scam to advertise either the content directly mentioned in the post, or something within the page that is linked from the digg post. If a post is dugg 2000+ times, do you know everyone that has dugg that post? do any of the names look familiar? Have you read the responses in there? Are the posts automated? What percentage of the voted actually posts?
