If the player writes one of the forbidden words in the chat, as a punishment, a wild mob will randomly spawn and its name is [Killer Mob]. you can change the name of that mob through config file.
And the health of that mob is also determined by chance. The minimum amount is 10 and the maximum amount is 100.
If the player has a weapon and armor, the same weapon and armor will be given to Punisher mob and can give a very high damage to the player.
