I just did the only thing I could think of to address the problem: 
I fed the discuss list to a script that sent a message individually 
to each address, with the address included in the message subject 
and body. The message is addressed as coming from discuss-admin at blu.org.

The offending address should bounce the message, and I'll then be 
able to identify and unsubscribe it. Unfortunately, it also means 
that everyone else will receive an annoying test message. Sorry for 
the annoyance, but I felt it was necessary to fix the problem.
