Here is what I just received today and I quote:
A customer of ours notified us that you have libeled us. We are filing a law suit against you today. We will be notifying your university about your ethics.
We will file suit to clear our name. If we file for an injunction, the cost is about $2,500. We'll be seeking compensatory and punitive damages for harassment, malicious libel and/or slander, defamation and tortuous interference. You'll need to pay us about $10,000. You will be forced to appear in Philadelphia Federal District court in a few days. If you don't have the money to pay us, your credit would be ruined for 10 years; and we'd garnish your wages.
Pretty sad state the world is coming to don't you think?
