Shipley has garnered attention for his work investigating individuals who claim to have served as SEALs or other high-profile military service claims. He and his wife Diane produced a series of
YouTube videos, "Phony Navy SEAL of the Week", which combined footage of Shipley telephoning individuals suspected of false claims and questioning them to determine if
stolen valor had occurred and how far the individual would persist in a deceptive claim. The videos also included interactions between him and Diane and video clips that related to the topic at hand. The YouTube series became a series of video segments which are privately hosted on his website
Extreme SEAL Videos on a paid subscription basis. In addition to a featured show in which Don and Diane travel around the United States to engage individuals who may have stolen valor, there are other video segments, including Q&A sessions, a cooking show hosted by Diane, and footage from the Extreme SEAL Experience training course. Shipley has also been a
Special Guest Contributor at 'SOFREP.com'. The site provides news and analysis from former military and Special Operations veterans. He states, "...the FBI estimates that there are 300 SEAL Impostors for every living Navy SEAL. Verifying at least a dozen and often over 20 fraudulent SEAL claims each day, I put the number much, much higher than 300." He estimates there are roughly 17,600 who have completed Naval Special Warfare training since 1943, about 10,000 of these are alive, and 2,400 of them on active duty. Shipley's YouTube channel was terminated on February 21, 2019. Shipley said he had been suspended previously, sometimes for months at a time, for making similar posts on YouTube about individuals who had pretended to be Navy SEALs. ==Other work==
