He isn't a "danger to the community" - he is a danger to people who put all their information on Facebook without knowing how to correctly use the privacy settings. Anyone can do this.
Yea, it was my fault that he was able to access most of the information he did, and it is pretty easy to find my last name.
Although in my defense, my last name is more uncommon then one such as "matthews," so if you search for me, you can easily find info on me, even without facebook.
One more thing, I don't want anyone getting this confused. I don't agree with the "danger to the community" argument, but he can still harass and cause trouble.
