After a brief lull, a new Facebook scam has just popped it’s head out. The new scam is spread through wall post updates of people where users will see a text saying "I was online on FB for 4007 hours in 2010! Use this great tool to check how much hours you spent online."
As you can see the message is enticing enough for users to click on to actually see how many hours they have spent on Facebook. However, this is a scam and clicking on this link will lead you to the app asking for permissions. Once you give it permissions, it will automatically post an update to your wall with a similar message and then ask you to complete some surveys.
The app is definitely a scam, because when I used it on an account created just for scams like these, it told me that I was online for 3988 hours in 2010, whereas as per my last recollection this account was only created in December and the max time I have spent online with this account can hardly go beyond a couple of hours.
Rest aside, do not click on this link and ask your friends who post such updates to delete it from their walls. Also if you are so keen to check how much time you spend on Facebook, check out some of our earlier articles.
