Under 1992 Anti-Terrorism act, American businesses are banned from providing any sort of goods or services to a designated terror groups like Hamas. Although the group has only claimed responsibility for one of the attacks named in the suit, attorneys for the plantiffs claim they have expert proof to link the terror group to other attacks. The suit also names members of Hamas and their Facebook accounts allegedly used for conducting terrorist business, in order to argue that Facebook has the ability to stop or block the organization, but has so far refused.
Facebook has yet to responded to the lawsuit, which was filed in a US District Court in New York, but the company did remind users to follow Facebook's Community Standards and to use the built-in reporting tools if they see unsafe or threatening behavior. On the other hand, a Hamas spokesman in Gaza told Reuters that the lawsuit was an Israeli attempt to use Facebook to spy on Palestinians.
