I don't think it works because I checked it on a domain I wanted to buy and the website I work for, said both were banned. That can't be right.
I've tested that tools but unfortunately is doesn't display the right results. One of the domain i tested has been banned but it still give positive result which other tools don't. The tools that give accurate result is : IsMyWebsiteBanned.com IsBanned.com
Wow, I didn't know domain names were band by Google. How can they ban a domain name? I would think they would ban a website due to violations but, if the website is changed or the domain expires and is bought by someone else; I don't understand why a ban would continue.
Have you ever faced this, you search something in Google and instead of result Google ask you to fill captcha. This happens when Google detected unusual traffic from your computer network. Same thing happens with freewebseotools_com. Tool website (freewebseotools_com) fetch bann result from Google and displays the result accordingly. But when there is excessive use of tool website in short span of time than, whenever tool query for result than Google ask the tool website to fill the captcha in order to get the result but tool website fails to do so than in that case tool website shows every website banned by Google. So I think you used the tool when it was temporally banned by Google.
" Sorry, we are unable to check the status because of system error. " all tools didn't show true information!
