What you are describing here is an alternate method of cancellation,
not a forgery of the main way of cancelling.

Of course, if they really want such an alternate method of cancelling,
let's write it for them, so that it also uses signatures to check
authenticity.

All the more reason to allow the backbone admins the power to not pass
anonymous articles.  It won't work, they'll feel like they're in
control, and everyone wins.
