With 500+ million people, 500= millions scams are bound to happen. Another one sleazy scam is now underway and it involves showing people "Really cool Facebook revolving images".
The messages is spreading virally and I had to delete around 9 messages from my wall recently. The scam looks to be spreading virally. As always do not click on this link and delete it from your wall if you see it.
P.S. I visited the site in question to see what it had to offer, but it is just a parked page, so nothing to write home about here. Safe Facebooking.
Update: Looks like this scam is spreading differently now. Users are now writing on other people’s walls with the text "Checkout 360 rotate effect on images. MUST SEE http://revolvingimages.info/fb/"
