I found "X-No-Archive" in wikipedia that was apparently honored by google when archiving usenet.
Keep in mind that all archivers probably archive the message anyway but might treat "X-No-Archive: yes" as a cue to not release that message to public queries. In other words, "X-No-Archive: yes" netnews posts are archived right alongside all the other posts and Google employees can find them in Google's repository of netnews posts.
I believe this is the case for two reasons:
- Structurally: Few search engine companies will throw away an
opportunity to collect data when there's so much for that organization to gain by indexing that data.
- Specific to Google: When Google took on DejaNews's archive of Usenet
posts Google's search engine Google released copies of posts labeled "X-No-Archive: yes" for a while.
Overall, I think people are better off understanding that their boilerplate is not binding on most people (if anyone) and they need to be more careful in what they send.
