I think some people live online in put-down or gotcha mode and their offline persona is the nice one because, if they acted in person as they act online, they may not live very long.
Would you walk into a bar and say to an older farang with a lovely young Thai female:
How long does she think she has to put up with a has-been like you until you die and she gets all your money?
But on the internet social web, routine.
