[analog-help] Strange referring site entries

[Sarah Lander]

I have recently started to see a few strange entries in the referring site
report. I get an entry for the site url like

xxxx:+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++++++++/

even though other sites in the list are shown OK.

Am I correct in thinking this is some kind of default response from Analog,
and is it possible to overcome it? Basically I'm guessing the D column in
the referring site report is going to be useful for tracking down the
corresponding log entries, but what to do when I find them?
