I found this website which I believe is based on Buysellads clone script. But it seems like a good concept. You buy and sell facebook posts on pages and price depends on the amount of likes a page has. The problem I see is that it is easy to increase likes to a page. The guy who owns the site is willing to sell it. Code: http://www.sharedposts.com/ But I would need a second opinion to determine weather it would be a good venture or not as It will need alot of marketing and management to make sure payments and facebook pages are legit. Thanks.
