This is like antibiotics. The natural selection process will push people to use more secure communication methods etc. The conclusion, for me, is that repression is not the way to go and makes the problem only harder to monitor and control. The strategy I would follow to address this problem is to identify the mechanism by which these type of behaviors reproduce themselves and contamine new people. This is where to target. And again, not in the Rambo way, in a chess way where everything is kept under control and will lead to the final check mate.
