This plugin bans combat logging in an efficient way. Whenever a player successfully hit a player with a weapon or a potion, it will tag both players as in combat. After a configurable time, the tagged player will no longer be tagged as long as the player hasn't been hit since tagged the last time. If a player logs out while being tagged, the player will be killed automatically and a message will be broadcast to the server, but again all this is configurable.
