if(GetPVarInt(playerid, "lastcommand") > GetTickCount())
{
    SendClientMessage(playerid, 0x00FFFFFF, "Slow it down on the commands!");
    SetPVarInt(playerid, "lastcommand", GetTickCount()+500);
    return 1;
}

SetPVarInt(playerid, "lastcommand", GetTickCount()+500);

Put that either in OnPlayerCommandText (for all the commands) or at the PM command.
