I believe the $500 per unauthorized fax payable to the recipient caused some "blasters" to wake up, when they realized how XXX times a $500 bill will wipe out a whole lot of profits from the small percentage that might buy.
Permission marketing has replaced fax blasting to some degree. If you have permission to fax something useful once per business day, or once a week, you have better odds of making sales, without the risks associated with fax blasting.
The discussions on this topic died on FIB almost immediately when a big fax blaster was forced to pay thousands of dollars to those who had requested removal.
He had ignored all the removal requests, wrongly assuming nothing would ever change. Wrong!
