A man in Chiba Prefecture became irritated last month at how long it was taking for a barrier at a rail crossing to open. Losing patience, he fetched a hand saw from his van and removed the barrier arm so that he could drive through.

Unfortunately, another person recorded the incident on their phone and posted it on Twitter. The user apologized for capturing a few passing cars’ license plates, but believed it was important to capture the man’s behavior. The post went viral, attracting tons of attention online before ultimately being picked up by television networks.

When excerpts from the video were broadcast on TV, news programs blurred the man’s face. This is common practice for mass media in Japan, but this was only one of several recent incidents underlining how social media has changed such perception of privacy. Sites such as Twitter and YouTube are far more likely to encroach into someone’s space, whether the purpose is to shame someone for acting badly … or simply score some laughs.
