The following messages are currently appearing very rapidly. We've had to obscure the thumbnails as many people will find them disturbing.
Here's what the messages typically say:
[Video] - This is what Happend to his Ex GirlFriend!
Play Video! She could not walk properly for days!
Look what he did after her Ex girlfriend posted on his wall
lol What true pain both are having at this moment.?
Of course, there are people out there who find such links too tempting to resist. Here's what they'll see when they click on the link.
The victims probably don't realise that "Jaa" is Finnish for "Share", and they're helping the scam spread to their online Facebook friends. Typically such scams end up with you being taken to an online survey that will earn the scammer money.
Can I respectfully suggest that if you keep falling for scams like this, you try and get your kicks elsewhere on the internet? There's plenty of photos and videos of naked ladies out on the web which you can peruse at your leisure, without the risk of flooding the newsfeeds of your Facebook friends.
I've informed Facebook Security about this latest fast-spreading family of scams. Let's hope they can take swift and decisive action so their users are no longer at risk.
If you got hit by this scam, make sure you have removed the entries from your news feed (to stop them being shared amongst your friends) and check your profile has not any unwanted "Likes" under your "Likes and interests".
