Though there are many advantages of using WordPress but the default installation may open doors to many spammers. The comment form is the spammers favourite and the most abused. Hence it becomes necessary to filter out unwanted entries (comments) and keep the website clean. The best defence is to use a captcha system.
What is Captcha?
Almost all of the spam messages are sent by bots that can easily submit the form without using the form entry page. To avoid automated entries the Captcha system was designed. This requires that the user types in digits or letters from an image that in most cases may be distorted and randomly created, making it difficult for bots to bypass it.
Captcha plugin for WordPress
Here is a new captcha plugin for WordPress that you can use not just on comment forms but even on register and login forms.
This captcha WordPress plugin allows users to set captcha difficulty (Words and Numbers) and arithmetic actions such as plus, minus and increase.
