Adding a stone to someone’s territory simply adds 1 to their captures. Provided there are no moves left that generate points for either player, under Japanese rules, all moves lose points unless they require an answer (e.g. someone plays atari on a stone at the border). When answered, the difference is still 0. Most moves inside someone’s territory (at the end of the game) will lose points, others need to be answered. All of them are either a display of poor understanding of the game or poor etiquette.
