It's true what you said, but in this case, it undermines the true.

...I teach many people who don't know the site and I don't know them,
I see that they are the simple majority and
 don't understand very well about email and internet security,
..can you imagine the scammers taking advantage of these people?
 either they fall for scams and or they lose interest in meeting the original
because they met something that is not the real thing,
so she thinks she already met.. just an example..
