And an attitude like that is a perfect example why it can get dangerous.
Never underestimate a criminal or think you can outsmart them. You think you know their method and objectives? All it takes is for one of them to change the game on you, and it can turn ugly right quick - from complaints to your ISP to blackmail and personal harrassment/threats.
What if you think the game is the scammer is getting products for free, but the real game is identity theft? You are a guppy, my friend, and although there are some stupid and unsophisticated scammers out there, there are also sharks.
