MANILA, Philippines - If there's one person who could preach about using social media for social good, it's Chris Lao.

In 2011, Lao became Internet-famous for driving right into a flooded street in Quezon City. The incident was caught on camera, and the video quickly became viral: netizens were quick to brand him a rich kid with no common sense for driving into an obviously impassable street. His now-famous exclamation -- "I was not informed!" -- became the meme of the season.

But the reactions didn't stop, and soon they became more vicious and hateful: Lao became a victim of cyberbullying.

The cyberbully victim-turned-lawyer now speaks out to encourage netizens to think about the consequences of their social media footprints -- and to use them for social good.

Watch as Lao tells his story:
