Don’t copy that pole vault! According to the London 2012 Olympic “conditions for ticket holders,” you are not allowed to take pictures or video of the events nor are you allowed to “exploit” any video on social networks.
This means no Instagrams, no Tweetpics, no Facebooking (“OMG OLYMPICS!!”), and no nothing. In short, you shouldn’t tell anyone you went to the Olympics.
According to Petapixel, UK photographers are already being hassled for taking photos of the Olympic “city” from public places, which suggests perhaps that London should spring for a geodesic dome to cover the proceedings in mystery and smash cameras of errant Tweeters.
Perhaps there’s a reason Orwell set 1984 in London.
