AshleyMadison.com’s parent company is hoping to knock out more than 20 class actions filed over its 2015 data breach by invoking online arbitration agreements the plaintiffs signed when they subscribed to its matchmaking services.

The move to arbitrate comes after Avid Life Media Inc., which has been rebranded as Ruby Corp., agreed last month to pay $1.6 million to settle claims by the Federal Trade Commission and several state attorneys general over the breach, which compromised financial and personal information of nearly 37 million subscribers.
