I Got banned for GR 1.9. I dont know what did do but I think that my friend that sold me his Car its state value was 50k dollars and it was even upgraded that much but it had a medium tire so he sold that car to me for10k dollars and the main mistake I know that I made is that He sold me the car...

I got banned for GR 1.9 and i knew that what did i did wrong i sold my friend a car that was 1.7m dollars for 2m dollars because it was partially upgraded and i wanted money so we made a plan that i will sell him the car for 1.7m by G menu and then he gave me 300k in hand I know it is my fault...
