Subject: Re: [CC-User] Bogus DX Spot Attacks on Clusters

What happened this weekend was that tens of thousands of bogus spots were
entered into the cluster system.  These spots were all for SSB.   Since
there are no SSB skimmers available yet, all of these spots appeared to be
manually entered, but in fact they were generated by a computer.

Normally the human entered spots never are more than 60 per minute.  During
the weekend spots that were bogus were entered at many thousands per
minute.  These spots were targeting specific active calls.  These spots
were giving different frequencies on all contest bands for each bogus
spot.  These spots had same DX call and a different spotter call and
different originating cluster call.   This caused many nodes to get bogged
down trying to process all this data.  Some crashed.  Others got hopelessly
behind and continued sending data to my cluster which dropped the spots
because they were too old.  Millions of spots were being dropped.

My cluster limits the number of spots to 60 per minute.  This limited bogus
spots but also good spots in each minute.  When bogus spots stopped, then
all the new good ones got through.
