A video of a high school boy ranting rudely towards a female passenger went viral.
It was just the right kind of furore the Internet lived for. Judgement fell swiftly from keyboard warriors far and wide.
Lok-Yin, in particular, was thrilled to recognise the guy in the video.
It was his nerdy classmate, Chi-Shing.
To gain popularity on a local forum, Lok-Yin decided to start recording his other antics at school.
He shared videos of Chi-Shing’s daily humiliation and his personal details to a ravenous audience.
But the online mob were equally vicious to those who sought out undeserved fame.
Thus, with a crushing blow, social justice was served.
