I use honeypot fields, but you have to be really careful with them, and certainly do NOT just discard requests with the honeypot field filled, as the article suggests. About 6 months ago, the new version of Chrome started auto-filling email addresses into my honeypot field, so it was a good thing I returned a friendly message (explaining that some auto form-fillers might cause this error, and needed to be temporarily disabled) rather than just assuming "bot".. but I still had some pissed-off people who had been trying to give me money and couldn't. It's also worth noting that honeypot fields are only useful on a small site that is unlikely to be specifically targeted. A custom-tweaked bot can very easily bypass a honeypot field, of course.
