I dont know how to play on anni but almsot all players versus who i pvp hackers...I need record LP's i think?
You can't assume that all players that kill you, hack. Some might just be better in pvp than you and keep in mind that you aren't the only one who is helpoping. Admins have a life too so they have to spectate different players because we receive multiple helpops. If you want to do something about the hackers yourself, feel free to record them and report them on forums.
I think helpop only works when admins are nearby, because I always say what specific annihilation lobby it is, yet no admins come to the rescue.
