I have spammers spamming my "ask a > librarian a question" link, which _only_ results in email to a > librarian's inbox (several of them actually). [...] In that example, they get unfettered priority access to an inbox. If it's an easy form to submit, that's a high enough RoI for spambots. How is that irrelevant? As others have noted, a honeytrap field seems the most obvious addition to such a form. I'd also be fairly liberal with the blacklisting, as long as alternative contact routes are given (like how to reach a librarian in person or by phone). A two-step form would also cut the spammers drastically, in my experience, but then you're adding a little cost for regular users. A preview step might result in clearer questions, though!
