Facebook detected suspicious account activity

We've detected suspicious account activity....


It looks like your account has been spreading spam due to another person or website gaining access to some of your sensitive account information.

Sometimes this happens when spammers create a fake Page that offers you a great deal (e.g. free flight tickets) in return for a specific piece of information from your account, such as an access token.

We've secured your account and will help clean up any recent account activity that didn't come directly from you.
