Greetings --

The host's NAM has been blocked by the campus network folks
and the Student Judicial Affairs office will be dealing

It looks like the message was a multi-posted article.
The campus computer abuse folks referred to the article as
"spamming usenet with illegal money making scheme".

I have a list of Message-IDs but have never sent a control message,
let alone a control cancel message (that's how new I am).
