Keep your eyes open for this dangerous post. If you see it, report it immediately to Facebook and, whatever you do, don't click on the link. Here is a screenshot of the scam message.
If a user does click the link and enters their login credentials, the crooks take the scam to the next level and try to trick them into entering credit card information. While the credit card form does look like it was designed by Facebook, there's one dead giveaway that it's bogus. Can you spot the telltale sign that it is fake?
See the flaw? It's the grammar. The message at the top of the form is written in broken English that's barely readable. It reads "Payment page you were laid off, please upgrade your credit card again to return the payment in Facebook." Obviously, Facebook wouldn't have a jumbled message like that on an official payment page.
