This is a known “exploit” in almost any click-to-call system, but Valleywag is highlighting how easy it is to connect friends/enemies with embaressing businesses, thanks to Google Maps. Basically, find something in Google Maps your friend would feel weird getting a phone call from (like a sex addiction phone line, or the Republican National Committee), and click-to-call. When prompted for your phone number, just give someone else’s and enjoy your silly little prank.
Does Google offer a system for letting people block these calls, if they are are getting a hundred calls a day? I sure hope so.
