We may not achieve such, the little we can afford is in making scam accusation in this manner for others to see and be well aware of what is going on, it is expected that we got informed and try to avoid those websites, but when we lack the required security information and tips needed, we may ended being their victim, that is why it is also very important in making enough research on anything we do before hand, scam can't be eradicated, but we can prevent being scammed.
