multi-boxing .. is legal
harassment .. is not

next time, tell them you reported them for harassing you during your game play.

or just say "Ni Hao" from all your toons at once and walk away

sometimes, i miss SB and UO... at least in those games you could kill the ass-hats if they bothered you... and loot them bare and dance on their corpse. (not that i've ever done that... no.. that would be .. bad )

no one would dare mess with a multi-boxer if that were the case
