‘I have a domain name to sell you’ is a terrible business proposition

Since the Internet was born, individuals and businesses have been bedeviled by cybersquatters -- opportunists who buy up hundreds, even thousands, of URLs at rock-bottom prices and then sell them to the highest bidder, or extort protection money from people who fear the domain names will be used to besmirch their own names. They even generate revenue while they're "parked," since a random unused .com will generate some accidental traffic, which can be monetized through Google ads (www.Death.com is a good example of how this usually works).
