Spammers always seem to find ways to achieve their goals

You know the problem, you login to the control panel of your blog and you are met with dozens or hundreds of Spam posts. I hate that.

For example, this blog is “dofollow” … meaning, the links that are posted count in Google’s algorithm. So, if someone makes a good comment, they get rewarded. It is a win-win. But that also attracts the Spammers who see this as an “opportunity” to spread their crappy offers and sites.

For the most part, the Spammers use “bots” to automate the process and can do thousands of posts an hour. For you, to personal monitor those posts and clean them out could take a big part of your day, and that isn’t productive. What are your options? You don’t want to shut down comments, as that would limit the conversation. What makes blogs great is the conversation back and forth.

There is a solution. CAPTCHA.

CAPTCHA determines whether the visitor is a human or machine and the acronym stands for “Completely Automated Public Turing test to tell Computers and Humans Apart.” Seriously, that’s what it means. Almost as good as TWAIN (Technology Without An Interesting Name). The “word” is presented in a format that is slightly distorted so a human can read it but a machine can’t.

But there are a lot of different CAPTCHA programs out there…which one is the best?

According to Adam O’Donnell, director of emerging technologies at anti-spam firm Cloudmark, says,

“Google already has the best computer-vision techniques. The way ReCAPTCHA works, this means that Google will only be presenting CAPTCHA words that are very difficult for a bot to defeat,” O’Donnell explained.

“By pushing up that boundary, it will make CAPTCHA technology much better.”

The best part is not only does Google own the technology, but Google offers it free! I highly recommend you can take advantage of it. Unlike other CAPTCHAs, it can’t be broken by third-party apps to allow the Spammers to automate their garbage posts.

How it works:

• Sign-up for a reCAPTCHA key to get the code implemented on your website on the reCAPTCHA Administration Portal.
• Remember your reCAPTCHA key is valid only for the domain you sign-up with. If you need to have this option on your multiple domains then you need to generate different keys for each. Or you can sign-up with a Global Option.

Want to see it in action? Just go to the Comments section and you will see it. In order to post a Comment on this Blog, you have to go through reCAPTCHA. Now, will that block all Spam? No. But it will block the automated bots, which is 98% of the Spam posts out there.

Install reCAPTCHA on your site today. It’s free of cost and secure. You can also customize the look of reCAPTCHA on your website.
