Until recently, the only people who could call on a cell phone were the ones who were given the number. Now, a company called Intelius has created an online cell phone directory of 90 million numbers.

"Intelius requires people to use the mail, to fax requests, to make copies of driver's licenses and other things. It's clearly an attempt to drag their feet and discourage as many opt-outs as possible," said Ridout.
