Tired of Contact Form Spam?
Friday, January 25, 2008
Many of my customers have been receiving an increasing amount of spam through their website contact forms. The spammers fill in fake names, email addresses, phone numbers, and a junk message with lots of links. To counter these spammers, one must make the web-form difficult for a spambot to fill out and yet keep it usable for valued human guests. CAPTCHAS are used in a lot of places online, but randomized field names are preferable because no strain is put on a human guest.I presented a paper, called Spam and the Ongoing Battle for Safe Communications, on randomized field names at last year's Software Industry Conference.
Those interested in my help setting up a hardened web form on a business website can contact me. My standard rate is $95/hour.
