I have contributed a lot and am contributing to stackoverflow even today. The issue is I have seen so many good questions being closed. I had a clear solution for the question but were closed before I was able to post the response. Request: There should be a vote among high level moderators(fine if I cannot vote) before closing the question.
It is surely a fake since I saw two fake users (system users) bidding $100 AMEX gift card with more than 500 bids@ 75 cents per bid. I will even name the users vitar and rollthedice. I think after reading this post they will remove this two users and use brand new names because it won't take long for the users to figure out that they are bidding against fake users.
