I'm on the do not call list and use a "zapper" so my normal telemarketer frequency, aside from political and charity calls is very low. I did just register a new domain name and didn't configure my private registration for a couple of days... so I imagine my number could have been scraped from WHOIS.
So I put it out to other Slashdotters... have you experienced this? Do we have to look forward to a new level of spam harassment utilizing the latest and greatest in low cost automated phone banks? Has the cost of VOIP brought the cost of spamming down so low as to be profitable for the pump and dump scam artist?"
