Ok but if I find his dummy house he still has to get the mail some how, if he has that forwarded then theres a way to find this private mailbox at a shipping center thats not far from his new home. (even if it isnt a direct mail forward to the private mailbox it still gets there eventually so could rig a gps tracker in a package) Since he bothered to tell these details to nytimes I figured he probably made a mistake on twitter. Based on the tweets i'm guessing he probably setup his internet service in sept of 2018 and since he seems like a geek I feel like the odds are high he set it up soon after he purchased the home so then you simply look for homes in that area that were purchased by an LLC thats registered in nevada, wyoming, or new mexico in sept of 2018.
Edit: ....unless its not forwarded at all and he has a tenant living at the dummy house with instructions to scan all mail and email him the images
