Hello and welcome to Booty Master. If you take a few moments and read the help desk the solution to the Graffiti Spraying crime is given there. Honestly the best thing you can do as a new player is to connect with a gang so you can learn from the experienced players within the gang you join. The majority of the long time players in this game are helpful and are more than willing to assist new players in learning the ropes. Please feel free to contact me via direct message through the forum if you have any further questions.
