We have today contacted the FBI because all parties (so far) are US based and we do not have the experience of the American legal system to determine what actions can be taken.
We have proof (which isn't all stored on this server, so if the guilty person is reading this, there is no point trying to get into the server, the data is no longer on this machine) of who the person is and will be providing such proof, upon request, to the FBI. This is completely in line with our privacy policy which can be viewed at http://www.deardiary.net/common/privacy.php
In the meantime, I would urge people NOT to write anything that could be personally identifiable. Your information on the web is NOT SAFE. We can't state this strongly enough. There are some fruitcakes out there (and this one knows to whom I am refering) who feel its quite OK to hide behind their anonymity and frighten people with what can only be described as personal terrorism tactics.
I await contact from the FBI, however if you are the person doing the threatening you would be well advised to consider your position. What you are doing is illegal and immoral and you will be found.
