I think cold calling could be an even bigger nuisance. My DNS provider published my phone number by mistake on a whois when I registered a domain, I spotted it immediately and it was corrected within hours. Over a year later I still receive cold calls from India to sell me web services at least once or twice a week. Imagine if you can match everyone’s position with a mobile phone, a dream for tele marketers, tailors, scammers, etc...
