Justin Bieber Scam Alert!!

BEWARE all Justin Bieber Fans! 
There is a scam circulating on twitter and the internet targeted directly at Justin Bieber fans. I don't understand how people can scam kids like this. This is horrible! The ad says to use your cell phone and confirm a code and ignore the $9.99 message. Please be warned that this is a total scam. If there is such a contest I will definitely let you guys know.
