If you’re a Facebook user, it’s important to keep abreast of the latest scams that targeting the service.

The most harmful scams attempt to steal login details, but many try to trick users into completing short ‘security’ checks before they can access an enticing Facebook application.

These surveys checks may seem harmless, but not only do scammers earn money by conning people into completing them, but giving such applications permission to access a profile also allows them to spam a profile’s friends with the same enticing application — and so the scam spreads.

As with all scams, if an offer sounds to good to be true, then it almost certainly is and any Facebook friend requests to use applications that promise exciting new features (being able to see who’s viewed your profile is a classic scam) should be viewed with extreme suspicion.
