A threat against me was recently posted online. I have the IP address of the computer as well as the time of the posting. I also have physical access to the computer, however the computer does not require a login in order to use it. Does anyone have any advice on how I could go about identifying the person that made the post? My thought was simply to try to find other activity with the same orginiating IP address at around the same time, but other/better ideas are welcome.
