I remember doing some consulting with a medium sized porn site in the early 90's and they were selling to another company. One of my tasks was to generate fake traffic logs to make it appear that the company had alot more traffic than in reality, so as to get a higher sale price. So, knowing this is how the industry works in general, I would be highly suspect about any claims made by some web site about their traffic, and as a matter of fact I would want a right to inspect, prior to the sale, for myself, to make my own determination about real traffic numbers from the inside. When buying a house, the buyer has a right to inspect period, and its ironic that this same right to inspect does not generally apply to sale of businesses, when the sale price (and risk) is many orders of magnitude higher.
