Sorry, I'll just say that I've read stuff elsewhere. I don't know if TOS comes into play since I'm not sure if that counts until someone is charged with a crime, but I'll err on the side of caution for now.
Letter is at the link here too. Most legit link with photo of the actual letter. I read on fb about the letter being slid under the door but at the original link with video, the letter was sent through the mail with the address handwritten on the enveloppe (from the OP).
