We are all afraid of losing the friendly playerbase as that's the best part of the game. However I don't think advertising would increase the rate of bad players. If we double the amount of active players we'll also double both good and bad players. It shouldn't affect the ratio between good and bad players. We should get more players so there would be more resources to develop the game further.
