a better idea
insted of booting why not making the said player unable to move like with some holding like sla only that it stay on him without waring off after some time.
while the said annoying player is stuck the recall button is disarmed so s/he cant recall or log out.
then a very nasty mob come and kick the **** out of the player and kill him.
player return to life and get killed again and again untill all equipment s/he wear is completaly broken with extra repair cost.
then said player is auto kicked out.
it will hurt very bad in their pocket and maybe then people will stop being so annoying.
