The lawsuits were filed between last month and Monday by Ashley Madison users in California, Texas, Missouri, Georgia, Tennessee and Minnesota. They all seek class-action status to represent the estimated 37 million registered Ashley Madison users.
That follows the launch of a $760-million class-action lawsuit in Canada last week, in which an Ottawa resident accusses the dating site of failing to properly protect his personal information.
The U.S. lawsuits, which seek unspecified damages, claim negligence, breach of contract and privacy violations. They claim Ashley Madison failed to take reasonable steps to protect the security of its users, including those who paid a special fee to have their information deleted.
Ashley Madison is offering a $500,000 reward for information leading to the arrest of a group that hacked the site.
