Someone told me that my lil daughter uses VPN to use Facebook at my home. How does it work? Is it a site or software?

Julius is correct, those VPNpower spammers post their own questions, then get one of their own to answer. They then pick their own as best answer to give the impression that their answer is the solution to all VPN problems.
Typical behavour:
1) They post VPN related questions on several sub sections on computers on YA.
2) They usually post about 5 questions at a time.
3) They have just signed up on YA in the past few days.
4) Their person comes along and posts a stock answer promoting vpnpower web site as the answer.
5) The question user gives best answer to that fellow spammer, within short period of time. They ignore other answers, even better ones.
