Let me make a friendly suggesting PA.

The only indication I have that someone (or something) posted a
message here with the subject "Compare" is because you replied to it.

You seem to read and post to this newsgroup through the Micro$oft
technet server - which seems to have no capability to block the spam
in question (which was posted via Google).

For you, and all the other sad souls that suffer through the pain and
agony of the Micro$oft NNTP server, you might want to know that (some,
many, most) of us do not see those spam messages, because we are using
NNTP servers that are operated by people that have at least some clue
how to configure a server to detect and reject spam postings.

So my friendly suggesting is that you refrain from responding to the
spam postings that some (or many) of us don't see in the first place.
