For those of you who don't already knowm this plugin is a MUST and should accompany every single install of Contact form 7. For those of you who think CAPTCHA is ugly, doesn't work or has a client who is unwilling to allow it (yet still complains of spam on the regular), this IS the plugin for you.
Since installing on a dozen or so client sites, I haven't had a single spam complaint. Use this Honeypot to seamlessly integrate a spam or spambot trap into Contact Form 7 with literally a few mouse clicks. Stop spam in its tracks with a simple honeypot that reduces and even eliminates the need for CAPTCHA.
