Which famous people were found on the Ashley Madison user list?

The Ashley Madison data breach in 2015 led to the exposure of numerous users who had accounts with the notorious site, whose tagline was "Life is short. Have an affair." Among the millions of names were various public figures and celebrities whose supposed involvement became a subject of media scrutiny. People such as Josh Duggar, former star of TLC's "19 Kids and Counting," and Jason Dore, an executive director for Louisiana's Republican Party, acknowledged their connection with the site. Meanwhile, other alleged famous names could have been the result of false information since Ashley Madison did not require email verification, allowing users to sign up with any email address. Consequently, it's difficult to confirm the veracity of many celebrity connections to the site beyond those who publicly admitted their usage.
