George Clooney has been burned by bloggers recently, but who knew it would turn him into a vigilante? Angered by the existence of Gawker.com's "Stalker" page, Clooney has asked his peers to unite and "render these guys useless."
Flood their Web site with bogus sightings. Get your clients to get 10 friends to text in fake sightings of any number of stars. A couple hundred conflicting sightings and this Web site is worthless. No need to try to create new laws to restrict free speech. Just make them useless.
I think any webmaster who's been hit by junk traffic or denial-of-service attacks can appreciate that wisdom.
UPDATE: On reflection, my first take was too hard on George Clooney. If fulfilled, this would actually be a positive, people-powered development—instead of taking out his anger via the usual team of lawyers, a celebrity is politely asking people to get on their Blackberries and start spamming. And remember, Hollywood was using Blackberries when they were just a whisper.
