Why would they ban you for using a pin? Unless the person you buy the pin from doesn't pay for it, you won't get banned.
i mean like say ur country phone changes in 3 different pins isnt that paying not for ur self. like a fraud?
The ONLY way you can get banned for using a PIN is if the payment for that pin bounced (credit cards). And your account only gets banned until you repay the cost of membership and you get unbanned without any blackmarks.
