Tinder users at Austins SXSW festival earlier this year were the target of Ex Machinas clever but creepy campaign. Armed with a fake Tinder profile featuring a picture of the films star Alicia Vikander, the campaign started sending messages like have you even been in love? and what makes you human? before directing those who responded to a promotional Instagram profile for the movie. While its definitely an intelligent use of new social media and a clever tie-in to Ex Machinas artificial intelligence themes there was a bit of an outcry about the invasive nature of the campaign, not to mention the smashed hopes of festival-goers who thought they might have a chance with the lovely Alicia Vikander.
