Can we start to collect some data on errant programs that users
"use"? I have discovered that a rather prominent contester appears
to be using a program that, from time to time splurges out what
appears to be a binary dump of a text window on his (Windows)
machines. In 32/64 bit "wide characters". Perl just swallows it
and DXSpider logs it (in html encoded form). Fills up the logs
(and disconnects the user) but otherwise is "harmless".<br>

planning to voice my opinion. What you tolerate as a SysOp is
completely up to your individual threshold level. But, I have
basically outlawed any user on my nodes from connecting if using
HamClock. At one point, I had 6 users running the software 24/7.
I refer to this software as a "resource hog" because of how much
data it requests for every spot, then resends the users Name,
QTH and QRA every 15-30 seconds (which is probably the default).
I have a modest computer and cable modem setup for the cluster
and home network usage. If the connected user callsign appears
like this (AA4U), they are probably using HamClock. I will
usually ask the user to connect to a larger scale node, after
explaining why it's a resource hog.
