Most of us get spam trying to sell us things, most commonly prescriptions, cheap mortgage rates, online gambling and other, more "adult" topics. Most of us just delete them or hit the "spam" button and move on. There are some other types of spam that are a little more serious, however.

One of the most common ones has been around for many years - the Nigerian bank scam. The person sending the email pretends to be the wife, brother, lawyer, banker or have some other relationship with some kind of government official in Nigeria. They tell the sad story of money that was deposited in a bank account but can't be accessed because the person has died. They offer to give you a share of the wealth in return for accepting a transfer of the money to your bank account. The catch is, you need to give them your bank account information and transfer several thousand dollars to them first for "expenses". Naturally, you never see any of the money that is promised after sending the expense funds. It sounds obvious, but people fall for this scam year after year, even though it has been going on for so long.

Other scams offer investments with huge paybacks. They always claim to be risk-free naturally, but once you've sent them your money it's highly unlikely you'll ever see any of it again, let alone profit. A similar scam involves credit cards for people with poor credit ratings. You send them a security deposit and processing charge and they send you a credit card. Unfortunately, once they have your fees you'll never hear from them again.

Remember these offers are worse than even ordinary spam. Legitimate businesses do not promote their products by spamming. They e-mail selected groups, generally those who have purchased from them before or voluntarily offered an e-mail address. Other offers should usually be ignored. Simply hit your delete button. However, even highlighting the e-mail in order to delete it can signal a spammer that you received one.

How To Sidestep These Scams

Firstly, never ever reply to spam, either by hitting reply or by clicking a link in the email. These things will only serve to confirm your email address is active and you will shortly start to receive much more spam than you do already.

Never send any private information like credit card numbers or username & passwords by email. Legitimate companies like Paypal or your bank will never ask for these things directly through email.

Spam isn't an easy things to stop, but if you don't recognize the person sending you the message, and it sounds too good to be true, it probably is. Besides, how many dead Nigerian dictators with huge bank accounts can there really be?
