Pigman Infestation

Yes they don't hurt, and I quite like them when I visit the Gana Isha they welcome you.
 
Put yourself up as a sacrifice and do it for us or leave the things alone and walk on by. They don't hurt, unless you hurt them.
 
Ähm, you know that once pigman are aggro at one player they are aggro at ALL players, right?
I once had a nice situation where I went to the nether only to be instantly attacked by hordes of pigmen and dying fast.

He's Quite Right Attacking one Zombie Pigman causes the whole group of nearby Zombie Pigmen to become hostile and attack the player, like wolves. Zombie Pigmen will become neutral again if the player manages to escape; however, escaping zombie pigmen is extremely difficult as they are faster than a walking player (speed of .95 Blocks Per Second is the enraged zombie pigman's speed). If the player is attacked by a group of Zombie Pigmen, escapes through a Portal, and returns to the Nether soon afterward, the Zombie Pigmen will remain hostile. Since Update 1.4, Zombie Pigman have the ability to pick up weapons and armor of any defeated players. Thus meaning that since the Server Never shuts down only for restarts, you would have to wait for a complete server shut down or wait for an Administrator/Moderator/Player to kill them all for you.
