An advocacy group has published a first-of-its-kind comprehensive list of coaches banned from Olympic sports, creating a database of nearly 1,000 people no longer allowed to work in the U.S. Olympic system because of sex-abuse allegations, doping positives and other criminal activities involving minors.

The staff at greatcoach.com compiled the list using information from the U.S. Center for SafeSport, the U.S. Anti-Doping Agency and the more than 50 national governing bodies that oversee individual sports, most of which feed into the U.S. Olympic team.

The website, designed by former pro moguls skier Bill Kerig, was originally started to help families find certified coaches who are best qualified to work with their kids.

The SafeSport center and U.S. Olympic Committee have struggled to publish this sort of comprehensive list, even as the fallout from the Larry Nassar sex-abuse scandal has left both organizations vulnerable to lawsuits over allegations they didn't do enough to protect athletes under their purview.

For years, the USOC let the NGBs operate under their own rules about who landed on the lists and whether those lists were made public, and those rules varied widely between organizations.

In 2017, the SafeSport center opened and began publishing a list of banned coaches, but that list was restricted to those who had been banned since the center's opening. -sports
