Painting is the act of building on a player's Town Centres, or within the area which is revealed at the beginning of the game, in a way which can unfairly restrict movement amongst a player's base. Although it is usually referred to as something which occurs at the beginning of the game, it can occur any time, such as building in someone's farms.

Although it is not cheating, it is very poor etiquette, as it can potentially restrict a player's movement completely.

This is not to be confused with landgrab.
