These are some of the fun cheats you can use:
1.To travel through people's houses: you can buy an U.F.O and race through walls. Or if the house has a driveway connecting to on of the walls you can ride on it and quickly go through the walls.
2. To go to the website if it is blocked:
type https://www.chitchatcity.com. If it does not work, I can't help you then. You have to find a way to get unblocked... I don't know anyone's passwords!
Well I hope that you have learned a bit.
