Here's an email sent 8/18/07 from Gmail User: jimmark55gmail.com. It is ridiculous and definitely threatening in nature. Please report these idiots to Google so they will be blacklisted. See email below:

This is the only way I could contact you for now,I want you to be
very careful about this and keep this secret with you until I make
out space for us to see. You have no need of knowing who I am or
where I am from.I know this may sound very surprising to you but
it's the situation.i have been paid some ransom in advance to
terminate you with some reasons listed to me by my employer.It's
someone I believe you call a friend, I have followed you closely for
a while now and have seen that you are innocent of the accusations
he leveled against you. Do not contact the police or try to send a
copy of this to them,because if you do, I will know,and might be
pushed to do what I have been paid to this is the 1st time I turn
out to be a betrayer in my job. I took pity on you,that is why I
have made up my mind to help you if you are willing to help yourself.
Now listen,I will arrange for us to see face to face,but before
that, I need $6000. I will come to your home or you determine where
you wish we meet;I repeat, do not arrange for the cops and if you
play hard to get, it will be extended to your family.Do not set
any camera to cover us or set up any tape to record our
conversation, my employer is in my
control now.
Payment details will be provided for you to make a part payment of
$3000 first,which will serve as guarantee that you are ready to
co-operate,then one of my boys will deliver a copy of the video
tape to you that contains his request for me to terminate you(I
tape recorded our conversation),which will be enough evidence for
you to take any
legal action against him.i advice you be fast about this before he
   employs another person for the job. You will pay the balance of
$3000 once you receive the tape.
   Warning; do not contact the police, make sure you stay indoors
once it is 7.30pm until this whole thing is sorted out,if you
neglect any of these warnings, you will have yourself to blame.
You do not have much time,so get back to me immediately Note:I
will advise you keep this to yourself alone, not even a friend or
a family member should know about it because it could be one of
them.
contact me for now on this e mail : bright_1972hotmail.com
Good Luck.
