Because laws are made by mafias in power, and what is allowed today may not to be allowed tomorrow (that is the current trend in the western world). Some people might no like so much freedom being taken away, one day you might be one of them (I hope for you in Thailand that you will be spared that and that life tastes more freedom). And if that day comes, and you have let them in the past wrap you up nicely and disclosed every things to the mafia, well... you won't have much other︀ choice than submission.
I would be one of the psychopaths or brainwashed monkeys from the︁ mafia side, I would definitely target people on this forum. Innocent or not, I would︂ still get some nice hit. Better not be caught in that.
