Fake testimonials on Facebook!

[craig99]

Fake testimonials are illegal if I am not mistaken and yes by them showing other people/your friends that you have used it even though you have not they maybe tempted to use it so in turn it is fake advertising.

[Alexis Wilke]

By law there are several cases that I know of where lying is indeed illegal:

* To a cop (or equivalent) on duty
* To a customer through advertising (i.e. Hype)
* To a clerk when you are getting married (i.e. are you currently single?)

Other forms of lying are not controlled as far as I know. (i.e. cheating and lying about it will not get you to jail, just out of wedlock.)

So... I would say that Facebook is in case (2) -- people through the FTC could go after their butt...
