to hack my comp. because he lost a game. with bad lan?

block the user with the block button... :-D

yes i would report him...i think you would contact whatever site you were on and report him....or perhaps contact whoever you get internet through..

report him on the web site then tell him its just a game and its not about winning or losing its about having fun

I don't know if this will be of any help.http://help.yahoo.com/help/abuse/
