Lets get real here, eventually we all are here to earn somehow, through our respective ways of course so what's the point of pinpointing newbies?
This is your assumption. We "like to earn" does make any compulsion to earn and "somehow" is sounding like that you are not caring about the right way or wrong way.
if they are doing it after doing proper research good for them and even if they are not doing it with some research and get to know that it's some scam that's even better for them because this is how some people learn. Accept their ways and most importantly respect them as well. No offence.
Did your country give license to drive in road even if they do not know "how to drive" right now, it is fine. They will eventually learn after doing couple of accidents, might be killing some people in learning. Ohh! we should respect their way of learning "how to drive".
