In the 21th century, spamming could be one of the most annoying problems for a website. Especially if you use some publishing platforms like WordPress, your blog WILL be spammed and no default methods will save you from such nightmare. This plugin utilizes the popular anti-spam library, Google reCAPTCHA, to help your blog stay clear of spams.

The new no CAPTCHA reCAPTCHA, Contact Form 7 and Akismet are supported out of the box.

2.0.2 (2015-10-30)

• New Features

  • Display recaptcha error code when an unknown error occurs.

• Bugs fixed
