Dear casascius.
Today I found in my email a spam coming from your website and IP-address, advertising for your website casascius.com. Sending such unsollicited email to people in my country is a crime. In addition, because of costs of spam for me, I also charge per spam, feel free to pay the bill by sending 100 bitcoin to: 1DESYhdFBUdQyTWBpLif6BQdr3FRcKBHWL
The spam email you are referring to advertises casascius.NET, not .COM. You're billing the wrong person.
