In the AMA forum, a user indicates knowledge of a post I made coming from a "PA IP address."

As he's not an Admin on RCU, how is it that he's got access to RCU IP log data? Who's providing that to him?

It may be possible to glean that information from the metadata in the actual picture itself. A whole lot of info is there, including the location where the picture was taken, ID of device that took picture, and whether or not anything was modified (it is possible to clean or modify metadata). I recently learned lots about phones and what info others can get from them, as I served on jury duty on a federal trial.
