Fallout from the high-profile hack of extramarital dating website Ashley Madison is showing no signs of slowing down. A pair of Canadian law firms has filed a $578 million class-action lawsuit against the site’s owners, Avid Dating Life Inc. and Avid Life Media Inc.

Ontario-based Charney Lawyers and Sutts, Strosberg LLP filed the suit on behalf of Eliot Shore who said he joined the site for a brief time after his wife lost her battle with breast cancer. Shore maintains he never used the site to cheat and didn’t even meet up with any other members of Ashley Madison.

The law firms say the suit was filed on behalf of Canadians that joined the site whose personal information has since been leaked.

Ashley Madison didn’t immediately respond to a request from the Associated Press for comment. The site has said that the leaked user data doesn’t prove the infidelity of its members.

An earlier lawsuit on behalf of an unnamed female plaintiff takes issue with the site’s “paid-delete” feature that promised to wipe out all records of use for $19. Many users that paid for the delete feature have, as a result of the hack and subsequent data dumps, learned that their personal information was never scrubbed from the site’s database.

Members of a hacking group calling themselves The Impact Team infiltrated the site last month and made away with personal information from as many as 37 million members. The attackers said the paid-delete service was their motive for the attack, claiming the company was scamming users by taking their money for the service without actually deleting their records as promised.
