Is someone trying to game StumbleUpon for a profit? or to cost someone money?

I was stumbling this morning while working on a problem in my application when I came across a stumble to NewEgg.com that piqued my curiosity. The URL looked like this…

It would seem to me that the user that discovered the page intentionally put in some kind of Google Adwords referral code. Why would someone try to do that? Would it make them money? Would it cost NewEgg money? Both? Neither?

I reviewed the user page of the StumbleUpon user that discovered this site, and found that his only other discovery was to cabelas.com where AdWords code is in the URL also.

I started a discussion on OpenDesigns.org, and as of this writing, have not received any feedback yet. Gaming “Social” websites is nothing new. Many a site has been banned from Digg, StumbleUpon, Reddit, and dZone for questionable practices and spam. I’m not sure that something nefarious is going on here, but regardless my curiosity has been peaked.

So tell me readers (both of them), am I onto something here?
