LOOK WHAT I"VE FOUND>>>>>>>>>>>>
Contact the cyber-crimes division of the FBI and file a complaint. This is a criminal offense and felony charges can be filed.
Also, you can get the full name and address and all contact information of any ebay member you have had dealings with. Get this information and file a complaint of stalking and harassment with your local police
dept, as well as the police dept where this person resides.
Also contact this person's isp
and file the same complaint.
Change your email address and do not make it available in your user profile at ebay. This means all of his contacts will have to come to you through the contact member feature of the ebay website
. Then there will be a log at ebay.
You should have had this person's name and address sent to you after they had won your auction. I suggest that you print out all of the threatening emails
and run them by an agent of the FBI. Here in Texas, stalking is taken quite seriously and a complaint to the governor activates the Texas]
. You should not wait until something physical happens.
