You likely log onto free Wi-Fi quite often, but how often do you read the terms of using it? Public Wi-Fi provider Purple decided to teach users a lesson, and added a spoof term to its Terms & Conditions (T&Cs) on its network of hotspots. In agreeing to that term, people unwittingly agreed perform "community service" which signed them up to clean portable toilets, hug stray cats, and paint snails' shells. Only one eagle-eyed person spotted the prank clause during the two-weeks it remained on the T&Cs. And no, the company doesn't plan to hole anyone to their word. (Mashable)
