Who were the individuals exposed in the Ashley Madison data breach?

In July 2015, Ashley Madison, a Canadian online dating service marketed to people who are married or in relationships, was the victim of a data breach. Hackers associated with a group called "The Impact Team" infiltrated the site's security systems and accessed user data. Following a demand to shut down the site, which was ignored, the hackers released personal information for over 30 million users in August 2015. This information included names, addresses, credit card details, and email addresses. The exposure led to widespread privacy concerns, public embarrassment for those involved, and even reportedly contributed to instances of blackmail and extortion. Notable individuals from various walks of life were among those whose details were made public, leading to scandals, resignations, and personal turmoil for many of the exposed members.
