posting without thinking

Proud youth gets into trouble because of their rash posting. They post without thinking of the consqeuences. Knowing that their posting is aiming at a majority group of people, they just post them onto the net. The net is like a public notice board. Everyone gets to read it. If you put it as private, for the privileged friends that you tagged, think again. One of the youth got "poked" by one of these friends when her private post got leaked. Perhaps those friends are just net friends. For various reasons, it just happened. Will this be a lesson to future posters? It certainly won't be the last.
