Adds honeypot anti-spam functionality to CF7 forms.
This plugin adds basic honeypot anti-spam functionality to thwart spambots without the need for a Captcha on your forms.
The principle of a honeypot is simple. While some spam is hand-delivered, the vast majority is submitted by bots scripted to submit spam to the largest number of form types. In this way they somewhat blindly fill in fields, regardless of whether the field should be filled in or not.
Contact Form 7 Honeypot foils these bots by introducing an additional field in the form which is visible to bots but not to humans. If this is filled out by the bot it will cause the form not to validate and thus not sent.
