Should online death threats be taken seriously ?

UrObsessionisMe: I want you gone from aol and if the only way to do that is to kill you..... Those words were taken directly from an AOL chatroom and the story gets darker.. She said shes learned to shoot a gun and actually was stupid enough to post a time and a place where my murder will occur ( this saturday at remingtons ) On the surface her words seem pretty ominous but when we look closer we discover that its just the insane rantings of a Hep C infected dickwhore who feels she has been victimized and abused in a chatroom.. And after seeing her picture all I'm left with is wondering.. Why is she worried about killing me when her upper lip needs shaved so badly ?
