The reason most websites aren't for sale, is because they're not for sale.

But that aside...

How could you stop people "bidding" $100m for their own site?

Anyone with capital, why would they waste their time putting fake bids down? If they're genuinely interested in a site - they'd approach the owner privately.

What is the value of this, beyond "ooo look how much this site is worth"? Don't you just become another flawed website value calculator?

Just some ideas.

Bingo. Why even give my money to a middleman?
