I sold a site at sitepoint (before they moved to flippa domain last year) for 25k. I set up the auction at night, went to sleep, woke up next morning with several bids and many PMs. Several of them offered me more than my BIN price. The site was sold is less than 24 hours. My investment: ~$25 to setup the auction. Just a wordpress blog. I think they changed some of the terms since moving to flippa and it is still ridiculously easy to sell a site through flippa. Looking at this auction, I have my doubts. Something is not right. It is also possible that the buyer is an idiot with extra cash lying around.
