I see a growing trend on Flippa where people are selling new sites and claim they have already made money. They say it's due to their "special marketing strategy" that they will give you with the auction. I see these auctions going up to $1000+ and more in the bidding. I just don't get it. The sites have 0 ranking and no backlinks. The only proof of income are screenshots of Paypal payments, but those could be easily altered in Photoshop. These sellers seem to have good feedback though. I am wondering if anyone knows what kind of marketing they are actually doing or is it all one big hoax? I don't want to spend $1000+ on one of these sites to find out if it is or not. I'd rather someone with experience on Flippa tell me. Thanks.
