David from this company sends hundreds of spam e-mails a day to fill up your mailbox making it unusable and when you call to complain he says the only way to take you off of his mailing list is if you place a printing order with him of at least $100 before taxes.
His webhost abuse@netfirms says it is not their responsibility because the spam isn't coming through them. It does of course direct traffic to them. And 163.com where the heavy all day long spamming comes from in Hong Kong won't respond.
This is blackmail and nobody cares.
The attitude of "David" is that if you don't do business with him you won't be able to do any business in e-mail at all!
