Nayanepalibabu,
Scam is funny thing to begin with.
I am not sure what exactly is not scam.

Scam i think is some kind deception. So all the moral standard is scam, so is all relationship.
Even the relation between mother - children is a form scam. This relation is some kind of idea in brain, some kind of manipulation. You are taught, influenced to think in certain way, to give importance to certain idea (be it religion, relation, nationalism, race, color of skin). In your whole life, you will try to conform this childhood influence which appears real to you but in essence that is just scam.

Your personality, that is the bundle of identification and constant conformity with some idea or objects, in reality is the greatest scam. So in this myriad of scams (actually there is just scam in very existence, now physicists are talking "is universe some kind of holographic projection?" ), to say some particular one is scam is hilarious as hell and only shows your utter dumbness.
LOL, another small scam!!!!
