So the final solution is:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if(newkeys & KEY_FIRE && ForbiddenGuns(playerid) && !pInfo[playerid][pLevel] >= 0) // firs this was IsPlayerAdmin but i need it to block admins, not rcon. ever since i changed it i got errors, help me fix
    {
        new pname[MAX_PLAYER_NAME];
        new zstr[124];
        GetPlayerName(playerid, pname, sizeof(pname));
        format(zstr, sizeof(string), "SERVER: %s has been banned! Reason: Forbidden weapon", pname);
        SendClientMessageToAll(0xFF1A00C8,zstr);
        print(zstr);
        BanEx(playerid,zstr);
    }
}
