This SPAMMER has faxed my fax machine, used my paper and ink to promote 'Hot Stocks On The Street,' something I have no interest in or use for, and have never signed up anywhere with any interest whatsoever. I have reported them to the government, state and local, and to several stop fax spam organizations, in the hope of getting them some jail time, financial punishment, etc.
Pros: none. Only bad engage in this kind of practice.
Cons: TOTAL CONS! Con artists and pornographers use SPAM.
