anti spam
i have a contact form with a honeypot and a captcha to help combat spam, but still get a regular throughput of offers for russian viagra, (which i don't need). ;-)
i was thinking, is there a way i can hide a select list item from display, which is visible to spambots but not to a user, (a variation on a honeypot i suppose) so i can further help filter out the rubbish we are constantly bombarded with ?
