It is a violation of the game rules to repeatedly attack otherplayers when their percentage of losable buildings (the so called bashlevel) dropped to zero. The standard bash levels are 33,% 33,% 25,%15% and 5,% but they may be different depending on the server you areplaying on. After a certain amount of time (also varies from server toserver), the bash level will regenerate, rendering the playerattackable again. One attack at 0% is allowed, since a player may nothave realized that his or her opponent has already reached rockbottom. More than one attack at 0% is considered harassment.
