Use firefox with the google search today data, was identified as robots to gather information was blocked, and why?
There are many possible reasons for this to happen - Your network may have many ones do query Google simultaneously - Your PC might being infected with some malware / adware and send automate query to Google - You or some people on the same network might use automate script made query and fetched too much data from Google. SEO software such as SEO Elite can cause this problem as well.
Did you use seo for firefox, seo quake or similar addons ? if so,then its pulling too much date from google in short time. so wait for some time and pass through the captacha.
Hi, In my own experiences, this would usually cause by using some SEO scripts on your computer like those seo add-ons for Firefox on some SEO tools for automatic querying Google purpose. You need to re-content your Internet and change your IP. All the best,
