if (dUserINT(PlayerName2(playerid)).("banned") == 1)
    {
        format(string, sizeof(string), "Your account has been banned by an Admin. Reason: %s", <Your reason variable here>);
        SendClientMessage(playerid, -1, string);
        Kick(playerid);
    }

Don't just copy paste, I'm not sure what your banned reason variable is, in your enum.
