NNK PK system

So, another player killed me, in the PK history menu, near the nickname of the player who killed me, there is a "revenge" button that allows you to find the player and move to him, but I still have to turn on the PK mod and lose my karma for killing this player. The question is, I killed this player once and 2/3 was written next to the "revenge" button, what will happen if I kill this player two more times?
