The online video platform YouTube decided to suspend the account of a retired Navy SEAL known for exposing numerous cases of stolen valor.

Known for his direct manner and incisive humor, retired Senior Chief Petty Officer Don Shipley used his YouTube account, tagged Buds131, as a hammer against military imposters, specifically Navy SEAL imposters. His channel was named after the Basic Underwater Demolition/SEAL training class with which Senior Chief Shipley graduated.

YouTube, which is owned by Google, said the account suspension was because Senior Chief Shipley divulged too much personal information about his targets online. However, he disagrees. In an interview with PJ Media, he said “this time I was told/emailed I was banned from a video I had posted several years ago about a phony SEAL, but after several years I doubt that caused it. If you ask me, it was because I outed Nathan Phillips. That Indian who masqueraded as a Vietnam vet. That video got a lot of attention and a lot of big lawsuits pending from it.”

Nathan Phillips is the Native American who claimed to have been a recon ranger with multiple combat deployments during the Vietnam War. Senior Chief Shipley, however, used military documents to show that Phillips’ claims were false. In fact, Phillips’ military records showed that he never deployed outside the United States.
