How to avoid being scammed...  some comments
IRO your article on scams. The article deals looks at the objective,  but why do sensible people still get caught? Two main signals that you must not ignore are to be found more in the realm of the heart (emotions) feelings engendered rather than in the realm of cold hard logical reasoning. so when sense the following passop!!
  1 Greed.. something marvelous at below cost.. something you want but cant afford..  something special because you are special and deserve better.. ice enticement.. The devil and his collogues partner with our longings and fantasies  to rob us. If the offer is for a limited time or a select few  or never to be repeated  let the warning lights go on.
2 Stress. The notification introduces some idea of an impending calamity .. act  now to avoid disaster.. fear ..pressure.. panic... must hurry.. must accept the help offered.... Any of these feelings   then hit the breaks.
