The quickest way to remove an entire site is:
A: Block everything in robots.txt - add this line into your file:
User-agent: *
Disallow: /
**B:** Set up and verify webmaster tools, then go to your dashboard, select Optimization
(left menu) > Remove URLs > Create new removal request.
When it asks you to enter a URL, just specify "/" (without quotes to signal the root).
Note! You'll have to repeat the verification / removal process for all of the subdomains as well
That *should* knock out your site within a few days.
In the unlikely event that doesn't work, do this:
**A:** Remove the robots.txt block
B: Add the meta robots NOINDEX tag to each page
**C:** Once the pages are completely gone (use site:example.com to check),
put the robots.txt block back on.
**Question for you:** Why exactly are you doing this? There might be a better
solution for added SEO benefit if you explain why...
Cheers,
