    Steve, I have a couple of ideas I may try to discourage the abuse.
    I'll post results if they work.<br>
    And another solution may be to encourage the author of hamclock to
    start his own node just for hamclock. He could then add all the
    features he wants.<br>

          <div> Steve, It depends on what data hamclock is seeking.  Why
            all the show/heading requests by every hamclock user every
            second? It makes little sense. Does someone know the
            originator of hamclock who may be able to offer a solution? 
            For dxspider could there be an automatic rejection of some
            or all commands by those hiding behind set/nohere? Before I
            start the pain of rejecting multiple ips, I'll wait
            patiently to see if another solution is offered. .<br>
