"Single Spotters" are stations who make only one dx spot in the whole
contest weekend. It is obviously fairly unusual for a contest operator
who is active to make only one spot, many make 10's to 100's of spots
during the weekend. It is common for DX'ers to make a single spot for
a rare dx station then turn off the radio, so lots of single spotters
for rare stations is common, but they also get lots of contest spots
from other stations. The key here is the percentage of spots that are
from 'single spotters'. A high percentage can be a sign of the use of
fake callsigns to spot yourself or a friend that you don't want to look
like you are cheerleading for... in any case, the use of fake callsigns
is an obvious sign of someone trying to deceive the world in one way or
another.
What the columns mean:
DX - the dx station being spotted
Total - the total spots for them in the weekend
All(%) - the total number of single spots and the percentage of the total
dxs(%) - the number of the total spots that came from dxsummit and the
percentage of the total they are. These are broken out because it is
very easy for someone to put in fake callsigns on dxsummit and it has been
a common source of abuse of the system.

5W0OU 132 10(7%) 1(0%)
PJ2T 391 10(2%) 3(0%)
5N7M 75 10(13%) 3(4%)
Interesting stations in this list are JH3AIU and IK6CWQ.
IK6CWQ is interesting because he was on 40m ssb being
spotted by a bunch of different stations from node
EA4RH-5. That node makes it even more interesting
because it is where a series of fake spots by K1TTT
for K1TTT were entered.
The JH3AIU spots were real interesting because they were
all entered on my node. The calls were all stateside
callsigns but the addresses were all from japan:
219.114.175.170
219.114.172.143
211.014.115.160
219.114.178.219
219.114.169.094
Interestingly JH3AIU is a previous user of my node who
has logged in recently from ip's like:
219.114.175.070
which are likely in the same isp's dialup block.

there is a whole series of spots, mostly for so8r by various sp stations.
Many of them have similarly badly formatted frequencies and similar
comments. But this one group stands out becuase of the spots FOR so8r
and the spot BY so8r from the same ip as others and with the same bad
frequency format as some others.

A series of spots for LZ1MS that includes a spot by LZ1MS. Also many
spots by w9's who all used the same Bulgarian IP address along with some
Bulgraians and a 5b4 station.

This group confuses me, but maybe they just don't understand the system
well enough to abuse it properly. All the IP's are from Portugual,
but obviously not all the stations are. The only common factor seems
to be some spots FOR ct7/lz3nd by other ct7/lz calls with some
spots BY ct7/lz3nd mixed in. But ALL the spots FOR ct7/LZ3ND are from
the other ct7/ calls... and the faked stateside calls were used to spot
other stations.
This is confusing because if I were trying to promote ct7/lz3nd in the
arrl contest I would want the most exposure in the states, but many
stateside users filter out spots FROM dx stations so those would have
been seen by less stations than the other fake spots for other dx.
