PvP ranking system anti abuse

[Thanna]

Hi I just wonder if you can modify the script that I have which is pvp rank system, here's the explanation, if player 1 killed player 2 and they have the same IP he will not received a point, but when player 1 killed player 2 and they dont have the same IP he will receive a point, thanks in advance

- script PVP Kill -1,{

OnPCKillEvent:
if ( killedrid == getcharid(3) ) end;
if (getcharid(0))
{
set pkill,pkill+1;
}
}

if ( getcharip(killedrid) == getcharip(getcharid(3)) ) end;
