People continue to register celebrity names because sometimes they get paid. I just read the post on ElliotsBlog.com about the UDRP on the Detroit Lions star player Ndamukong Suh. Elliot brought out some great points that are 100 % right imo.
Taken from that article:
Several months had passed and I checked out the domain name, CristianoRonaldo.com. It was listed for sale at 1500 pounds, a price I could not justify paying given my salary. I called my mother, desperately seeking a backer, and she agreed to lend me 1,000 pounds from her credit card. I called the seller, and eventually convinced him to part with the domain for 1,000 pounds.
I knew quickly I had struck gold. I put a website up and it made around $20 a day from its Google ads. I discussed this with a friend on DNforum.com, the now owner of Bodis.com, Matt Wegrzyn, and he agreed to buy it from me for $11,000.
Maybe another story like KateMiddleton.com selling for $2350.
So when people read that kind of story they are going to try. They should know these successes are not the norm.
