I had this done at the server level, and it was no big deal. Any message
which met the criteria we'd identified was locally canceled.

There was another header that was common. I don't recall it exactly, but
I think it was "NNTP-Posting-Host" or something like that.

My fear is that newsgroup subscribers who are unable to filter out the

participate in newsgroup discussion in the future.

remains a valid one.
