Which celebrities were exposed in the Ashley Madison scandal?

The Ashley Madison scandal, which broke in 2015 when the dating website for married individuals was hacked, led to a stream of user data being made public. Among those exposed were Josh Duggar, a former reality TV star from "19 Kids and Counting," who admitted to using the site after his name was revealed. Reports at that time also implicated other lesser-known celebrities and figures from various industries, but many of them did not gain the same level of media attention. Due to the sensitive nature of the data breach and the potential for false positives in the leaked data, the full extent of celebrity involvement has remained somewhat unclear, with confirmed cases only emerging when individuals themselves acknowledged their use of the service or when irrefutable evidence was presented.
