War With Spammer - reCAPTCHA AntiSpam Comment

What is captcha?

A CAPTCHA is a program that can tell whether its user is a human or a computer. You’ve probably seen them — colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from “bots,” or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.

reCAPTCHA helps prevent automated abuse of your site (such as comment spam or bogus registrations) by using a CAPTCHA to ensure that only humans perform certain actions.

1. It’s Free! Yep, reCAPTCHA is free. The only reason we might charge is if you require special services from us.
2. It’s Useful. Why waste the effort of your users? By using reCAPTCHA instead of other CAPTCHA implementations, you are helping to digitize books.
3. It’s Easy. reCAPTCHA is a Web service. As such, adopting it is as simple as adding 4 lines of code on your site. For many applications and programming languages such as Wordpress and PHP we also have easy-to-install plugins available. We generate and check the distorted images, so you don’t need to run costly image generation programs.
4. It’s Accessible. Most other implementations of CAPTCHAs block visually impaired individuals, who cannot read images of distorted text. reCAPTCHA, on the other hand, has an audio test that allows blind people to freely navigate your site.
5. It’s Secure. reCAPTCHA is run by the original creators of CAPTCHA and has the highest security standards. Many other implementations of CAPTCHAs can be easily broken.
