I've also been stalked by Jason Christopher Hughes, and I can corroborate that he exists and that he's very difficult to track down. He's changed his name twice since 2004, first in Texas (to Manuel Luis Arsupial) and then in Washington (to Michael Rudra Nath). He's a transient and changes location multiple times a year as well.
There have been criminal complaints made against him, by various people, in California, Washington, Texas, New York and other places, but — as people have noted — law enforcement doesn't make this kind of thing any sort of a priority. I had an active criminal complaint against him myself, in Merced County, California, from March 2010 to March 2011.
I'm aware of no fewer than twenty different people who've been harassed by this person.
