After playing for like... 4 days, I got banned for "suspicious activity" All I did was watch some ads to double my credits several times. I understand that it really is a fast and easy way to get credits and all cars, but I used an ingame feature, so I can't understand why you banned me only for using an ingame feature. Besides that, the game either lags because of my phone, which is weak, or because it lacks optimization. Also, one thing I hate is needing to pay in order to max a car.
