Early this month, 18-year-old Allison Stokke walked into her high school track coach's office and asked if he knew any reliable media consultants. Stokke had tired of constant phone calls, of relentless Internet attention, of interview requests from Boston to Brazil.

In her high school track and field career, Stokke had won a 2004 California state pole vaulting title, broken five national records and earned a scholarship to the University of California, yet only track devotees had noticed. Then, in early May, she received e-mails from friends who warned that a year-old picture of Stokke idly adjusting her hair at a track meet in New York had been plastered across the Internet. She had more than 1,000 new messages on her MySpace page. A three-minute video of Stokke standing against a wall and analyzing her performance at another meet had been posted on YouTube and viewed 150,000 times.
