I'm writing this largely in response to "jasonlotito", who appears to have a personal investment in this story being a lie. That's not the case, I'm afraid.
I've been harassed for close to ten years myself by this person, who's sent numerous emails to my employers — including Apple and Palm — claiming that I was a pedophile, a Satanist, a drug dealer, a serial killer and a variety of other things. He's sent pornography to members of my family and attempted to impersonate me on Facebook as well.
I had a criminal complaint against him, filed in Merced County, in March 2010. While there are "protocols" for dealing with these sorts of situations, in practice, the police rarely act on them if the situation presents any sort of an actual challenge, in my experience. They're under-staffed and ill-equipped to deal with this sort of thing.
The situation is complicated by the fact that the stalker is a transient who changes his location several times a year, and who's changed his name twice in the past eight years. He uses TOR, public WiFi access, a raft of Hushmail accounts, and other means to make himself more difficult to track down.
I have first-hand knowledge of no fewer than twenty other people who've also been harassed by this person. He's been doing this sort of thing back into the 90s, originally on USENET. He's since moved on to Facebook and Google+, and now Kickstarter.
I maintained a web site at extinct-marsupial.org for a number of years documenting this stalker's activities. I finally took it down last year after my ISP became unwilling to deal with the multiple bogus DMCA complaints that this person supplied them with on a monthly basis.
I'm on Facebook, Google+, Twitter and other places; my personal web site is at shugendo.org. I've been a professional technologist for three decades, and I can confirm that the person harassing Rachel exists, has been harassing her for a number of years, and that law enforcement has proven completely incapable of doing anything about it, for her, for me, or for the other people that this stalker has victimized and continues to victimize.
