"Empty" isn't a person. "Message_Wall:Empty" is the default value for "Threads" which do not have a specified location, and in the case of a deleted thread notification, such as the "Message from the GNAA" notification 4 days ago, clicking it will bring you here.

There are a variety of other bugs which may also cause you to end up here. Are you referring to the "Message from the GNAA" notification, or is this regarding something else?
