Social media moves faster than anything else out there, writes online marketing guru Neil Patel, on the destructiveness of the Internet. A moment of dumbness can go viral and turn into a nightmare of mob justice out of control.

Take the recent case of a young man, Mr Edmund Zhong, who posted on the Channel NewsAsia Facebook page that he wanted to throw an egg at Law and Home Affairs Minister K. Shanmugam. This was after an egg-throwing incident in Australia when a teenager egged a senator for insensitive remarks in response to the Christchurch massacre.
