You may have missed an earlier part of the discussion where an example of
some non-callsign looking spot was used to mark the emergency... say for
example instead of spotting the callsign of the net control you spotted
"EMERGENCY/NET". Great, that would stand out on the bandmap, if it made it
that far. However, if that spot was put in on dxsummit it would get
filtered out and not make it to the cluster network because it doesn't match
the pattern of a callsign. It may also fail other filters if put in on the
cluster network... and if it made it through the callsign validity checks it
would likely get filtered out of many stateside bandmaps during dx contests
because it would look like a /NE prefix meaning stateside. It may also not
mean much to non-english speaking/reading users in other parts of the world.
