Man I want some KFC right now after reading this story. Five students in China found a way to use technology to get an unlimited amount of free chicken vouchers.
One of the students found a glitch with the KFC App - "The glitch meant that, for six months, Xu was able to manipulate a promotional voucher system to the sound of £6,500."
After that he started sharing the glitch with his friends AND then he got greedy and started selling the vouchers to people. That's when KFC realized what was going on and now the original five were taken to court and it was ruled that they had committed fraud. They were sentenced to 15 - 30 months behind bars.
