According to Graham Cluley, the offered link triggers the application permission dialog of a rogue application named "Update your Acc Urgent", which will supposedly allow the user to keep his or hers account.
A click on the "Allow" button adds the application to the user's profile, and allows it to - among other things - to post status messages or other content on the user's Wall - which it does immediately by posting the same message the user fell for.

Users who have fallen for the scam are advised to delete the application and any messages it may have posted on their Wall.
