It usually ends up being a CAPTCHA implementation people add for this
purpose, because it's difficult to find a modest, _simple_ plug-in for
WordPress, only baroquely complex ones. But a complete solution would
be anything that asks the user to answer a simple question that isn't
standard across everyone else's WordPress, like 'What is 4+5?' and
require a correct answer before the form submission gets processed.
Bruce Schnier on his blog ('Schneier on Security') has a simple hack
where you are asked to answer the question 'The title of this blog is
"Schneier on ________". What is that word?' (I paraphrase.) Works
perfectly -- because it's not necessary to defeat custom attacks, just
comment-bots aimed at commodity software.
