Wow I cant Believe I Got My PROFILE & PHOTOS Stalkers – Facebook Scam
Scam Type: Rogue Application, Survey Scam
Trending: March 2012
Why it’s a Scam: Clicking the wall post link takes you to the following Facebook application. Clicking “Allow” will give the permissions shown above to the scammer. The application will be able to post to Facebook as you. This will allow them to spam their scam messages to all of your friends. Do you really want to let an unknown developer have this much access to your Facebook information? This particular application is called “Pr0file stalker”, but scams like this are known to use multiple Facebook apps.
Safety Tips: Anytime you install a third party Facebook application, you give the application developer access to your personal data. Always be very selective on the apps you install, and only install them from well-known, trusted sources.
