Trying to get free platinum (outside tapjoy offers, or tournaments...) gets you banned anyway. You can try and contact support(at)spacetimestudios.com, but I seriously doubt they can/will do anything about it to be honest. I mean, you basically tried to get plat outside of the official STS environment, meaning you tried to scam STS of their real life money. Best thing to do is try and start all over again, if your device isn't banned forever by now.
As said so many times already, if a deal sounds to good to be true, it usually is.
