Last year, Ashley Madison, the extramarital-affair website, experienced a widely publicized data breach. Some information was leaked, and some information was held for ransom. The breach compromised the personal information of 37 million users.
One allegation put forth as a result of the leaked information was that Ashley Madison created fake female profiles on their website. These Fembots (Female Robot user profiles, a reference to female robots in the Austin Powers movies) were created to lure men into purchasing accounts.
This claim has led to a class action lawsuit in the U.S., and is the subject of a dispute over whether litigants can use hacked data released to the public in their case (see this motion). Basically, it asks “Is leaked data in the public domain”?
