Well, obviously what FB doing is connecting socially all people. There is WATSAPP, HIKE, WECHAT, LIKES and more grows every day. So don't bother even to think FB going to be Google some day..
But with FB will be really suitable hackers network. And you can earn lots of money online..
Like few days ago my friend said he cracked the new Norton360 and put it on Facebook with a small change. And he earning millions now. He just on the Norton360 remote access and added a alarm app with it. When you use his crack/patch, Norton360 (and others) automatic on the remote of on his PC and installed up running and store a small file alarm which connect to internet and show the PC/device has network, he has a status board where he can see each of the PC/Devices, IPs, exact location, what site they browsing and everything even can on the camera if the device has. With is he access those PC/Devices and get their ID and PASS, CC, Bank accounts and everything and earning hugh money every day.
So see.. it's only possible because people like FB and trust it and HUGH real human traffic.
P.S. Maybe you are using his crack/patch right now at your PC
Thanks
