Honeypot Anti-Spam for Contact form 7
This simple addition to the wonderful Contact Form 7 (CF7) plugin adds basic honeypot anti-spam functionality to thwart spambots without the need for an ugly captcha. The principle of a honeypot is simple — bots are stupid. While some spam is hand-delivered, the vast majority is submitted by bots scripted in a specific (wide-scope) way 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. This is how a honeypot catches the bot — it introduces an additional field in the form that if filled out will cause the form not to validate.
Google Captcha (reCAPTCHA) plugin
This is an effective security solution that protects your WordPress website forms from spam entries while letting real people pass through with ease. It can be used for login, registration, password recovery, comments, popular contact forms, and other. Users are required to confirm that they are not a robot before the form can be submitted. It’s easy for people and hard for bots. You can add this ReCaptcha to any other form or even the WordPress admin login page also.
