3) I get two books mailed to me that I didn't order, when i contacted the site that sent them they could only tell me the first name is given and it's not anyone I know or anyone who'd send me books. The books were "The little price" and "George Orwell 1984".
Wow, that's crazy! Did you look through the books/binding and/or packaging for a listening device or some other type of sensor? In the context of drug cultivation investigations, I've heard of "bugs" being planted in packages that people bring inside.
Unless mining is illegal in your jurisdiction, you could go to the police and tell them what you've shared here. If they were investigating you, thinking you were running a grow operation, they would probably be very happy to learn you're just mining. Might want to take a look at your rig to verify.
