[thelist] hidden form field anti-spam tool?

[Joel D Canfield]

just read this in a comment at jzeldman's blog:

    "hidden form fields are (currently) an excellent means of getting rid of most spam. The trick is to put a text input field on the form, and then use CSS to hide it. Human readers will not see it, but spam bots will. Thus you can safely discard any message that fills in the field."

what's the downside?
