This sounds like those ********bags at Sunlit Computer Traders on the Gold Coast AKA The Late Mail, Hitman Oz Racing, Master Trading room (they start a new name each month). They started posting a free tip each day but obvioulsy no one was buying their service.
I heard yesterday a Lady down South was awarded a judgement against them for the return of her $10K purchase price of last year, due to fraudulent manipulation of their trial pages, they didn't turn up for the hearing!
