It is impossible to get free VIP outside of a VIP Guest Pass, which can be obtained as a prize through Jobs, or by redeeming a cash card (you will be given a 3-Day VIP Guest Pass in either case).

Do not trust the messages you see on your page about free VIP. They are all fake, and designed to steal your account and information without giving you VIP or points. For more information, see the VIP FAQ.
