You could join a class action with the evidence that's out there already. More likely than not, if you're using FB, your data was compromised. Don't know when you stopped using FB but when you "delete" your account it isn't really deleted.
Starting the class action is more work. Need to find a law firm that will represent the class in return for a percentage. If it's a winning case, that won't be hard to find.
