Too Good To Be True

It seems as if person after person is falling for scams that are so obivious.
One example is where a person receives a phone call and is told that they need to give information to the caller in order to get their rebate.

Another example is where people seem to think that money should rain on them and that they win some foreign lottery without even entering. Come on people, think about it. How can you win something if you did not enter? Why do people fall for this scam? Greed, plain and simple. The desire to get something for nothing is what cause people to fall for this scam.

Someone you never met before wants you to cash some money orders for them and send them the cash. They usually offer to let you keep some of the money for your trouble. This person usually finds you through a dating site or simply IMs you out of the blue. They will chat with you for awhile to establish a rapport, then comes the big bang. Don't fall for it. If you refuse, see how quickly the person who professed he loves you drops you.

Common sense says if it is too good to be true, then it is. No one rains money on you.
