Ok so my friend was telling me that he uses ping zapper so that if hes account is banned he can say he got hacked and just so blizzard cant just ban his other accounts ect. But when I tried ping zapper and battle ping the game logged me straight in without even asking for authentication. If I was really on a new IP wouldnt blizzard ask me to do the email thing or at lease ask for authentication? Also I want my friend to be able to play my account for PVP rewards without getting banned for account sharing aswell n we thought ping zapper would solve this as well. Any info on how this IP thing and tunneling programs work would be great thanks.
