Each year, the Better Business Bureau compiles a list of the most popular scams. The BBB received an unprecedented nine million complaints during 2009! Below is a quick rundown of the Top 10 scams of the past year.

• Work-at-home schemes: This is routinely one of the most popular searches on our site. Google work-at-home offers are particularly suspect, as are those roadside signs promising "CEO Income from Home." See our list of legit work-at-home opportunities.

• Credit repair scams: Don't believe the promises about wiping out your debt in return for a huge upfront payment.

• Government job scams and government grant scams: Remember, USAJobs.gov and Grants.gov are the only legit sites.

• Mortgage foreclosure rescue scams: Again, never give any money upfront.

• Check collection scams

• Advance-fee loan scams: These target small businesses with promises of a loan in return for paying an origination fee.

• Mystery shopping offers: Remember, Volition.com is one of the legit sites Clark recommends.

• Advertising directory scams

• Free trial offers

• Phishing scams
