Very easy just make a bool

PHP код:

new bool:pm[MAX_PLAYERS]; 


And at the pm command

PHP код:

if(pm[iPlayer]== false) return SendClientMessage(playerid, -1, "This player blocked private messages"): 


And for the command

PHP код:

CMD:pms(playerid, params[])
{
    if(pm[playerid] == false)
    {
        pm[playerid] = true;
        SendClientMessage(playerid,0xEE128960,"Private Messages unblocked! You can receive messages from other players");
    }
    else
    {
        pm[playerid] = false;
        SendClientMessage(playerid, 0xEE128960,"Private Messages blocked! You will no longer receive messages from other players");
    }
    return 1;
}
