Dear Friend, I need to remove my indexed pages from google but i have no access to my hosting account to use a robots or a meta tag because my account has been locked due to some irrelevant excuses.The hosting is returning 1 400 htpp error for my site.Will my site be removed from the google's index if i use the google's removal tool.Google says that you must return a 410 or 404 error message, but there is no way i can change the 400 error to 1 410 because i have access to nothing.I only have access to google's webmaster tools. What do you suggest ? Thanks Best Regards.
have you verified your site with "Google Webmaster Tools"? if you haven't verified and don't have access to your site, there is nothing that you can do.
You should still have access to your domain name, change the DNS server to a new hosting company and reupload your site. Add your robots.txt and your problem is fixed.
