It would be really, really rare for anyone to design/maintain a
_site-specific_ spambot for just one target site. What exists out there
are generic, site-independent scripts that roam the Internet looking for
any Web forms whatsoever, and blitz them with submissions. (It get an
insane amount of submissions to the links feature of my PerlHoot-based
knowledgebase at http://linuxmafia.com/kb/ , and none of that ever makes
it to public display because all submissions are moderated, but that
make no difference, there being no intelligence whatsoever behind the
spambots.)
So, in general, having a site-specific "answer this trivial question"
feature is more than sufficient protection -- because the spam is
overwhelmingly fully automated.
