Using CAPTCHA is probably the most effective way to prevent automated spammers from submitting your contact forms on your site. But sometimes the two words are difficult to read. In response to these challenges, I have developed a new feature I call "stealth mode". Quite simply, spambots crawl the web and look for forms to submit (by finding the tag in the HTML). Stealth mode removes the form tag, thereby making it invisible to bots. But people still see the same form and submit button. When the form is submitted, it instantly creates the necessary form tag in the HTML and submits it normally. Please note that this feature is experimental. To start using it, select "stealth mode" from the "spam protection" section of your form properties (where you normally select CAPTCHA).
