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.

Following further inquests about the ban, YouTube responded with an email statement: “YouTube takes harassment and the sharing of an individual’s private information, like home addresses and phone numbers, seriously and we have strict policies against it in our Community Guidelines. We review flagged content and remove inappropriate videos or terminate channels according to these policies.”

But this isn’t the first time Senior Chief Shipley’s YouTube account was banned. It’s been suspended numerous times for violating YouTube’s terms of agreement. “I have been in YouTube Prison before when phony SEALs would cry to them about being posted,” he stated in his interview.

People recognize that Senior Chief Shipley is doing good work through his channel. Before the suspension, it had over 230,000 subscribers. It remains to be seen if YouTube will revert the ban or maintain it.

Senior Chief Shipley also runs the Extreme SEAL Experience, which is an immersive program that prepares individual who aspire to become SEALs for the rigors of training.
