The legal name for the "moderate misdemeanor"-level crime of causing someone to be deluged with junk mail. Often performed by a disgruntled acquaintance of said individual as a way of getting even with the person for a perceived wrongdoing, and usually accomplished by "anonymously" contacting multitudes of businesses/organizations by phone/fax/email and/or responding to paper/internetjunk-mail ads that you yourself receive by filling out the advertisers' response-forms in your victim's name, so that he will soon begin receiving tons of useless crap in his mailbox and/or e-mail account, receiving innumerable telemarketing/sales-calls, getting loads of junk-faxes (which of course will create the added headache/expense of his having to buy more paper and ink for his machine from its dutifully printing out all those useless ads!), having salespeople knocking at his door at all hours, etc.
