"Somebody" can do this only if they have write permission to the 
Site.NotifyList page, which is password protected by default
(along with most other pages in the Site group).  I would not
recommend having this page open to anonymous editing.  And when
the form-based system is in place, the page can be locked against edits
except by the admin.

Alice would get "thousands of tiny mails" only if there were 
thousands of posts.   Even pmwiki.org isn't *that* busy.

*sigh*  I'm way ahead of you here -- PmWiki *already* merges multiple
mails to the same address.
