Interesting idea. I'll explain why I don't think that will really work so some people.

At the place I used to work, we offered access to mailing list archives through several mechanisms - ftp, web (direct access to mbox format files), email access to mbox format files, hypermail archive. Now the hypermail archive is generated from the mbox file so we couldn't leave the offending message in the mbox even if hypermail was clever enough to skip over it.

In reality I don't think it would be a problem for us as we'd generally be told pretty much immediately if someone needed to 'unsend' a message.

Alternative approach would be to replace the offending message with a dummy one - possibly with some special message-id so that it isn't shown by hypermail but is counted. Actually - that solves the problem for us - put the msgid of the message into your "blackmail" file and replace the body of the message with text indicating that it has been removed.
