pawn Код:

if(pClan[i] == 1 || pClan[i] == 2 || pClan[i] == 0)

This if statement will do the following:

If the value of pClan is either 1, 2 or 0, the message will be shown to the player.
I think you want to change that line to

pawn Код:

if(pClan[i] == pClan[playerid])

This will send the message only to players in the same 'pClan'.

EDIT: [XST]O_x beat me to it ;P
