Facebook scams keep on coming ... and Facebook keeps deleting

As a venue with a reported 400 million people sharing information with each other, Facebook is an ideal environment for running a scam.

Enticed with the idea of getting a "free" $1,000 gift card to Ikea or Walmart or Target, users are asked to sign up for (phony) fan pages that are designed to lure them off-site where they have to sign up for a dizzying series of offers. The actual deal to get the card -- if anyone indeed gets one -- involves applying for credit cards, signing up for subscriptions and joining clubs (for a monthly fee). Be prepared to withstand a mighty barrage of spam if you do sign up.
