I cant speak for what PYR legal can or will or has done but Mariner is faceless for a reason. If you want to contact them to have a report written all you can do is send an email. They have no phone number, no address, no employee names, comepletely faceless. and for a reason.
Their only public facing access point is twitter. (in my opinion) that's why PYR served them on twitter. It's the only avenue they have to publiclly reach them.
I even investigated their domain name to try to track down a registered company and they hide the registration of the domain behind another registrar through the Bahamas. They've taken significant steps to hide their real world identity.
