title: GOOGLE: how to prevent subpages from appearing in results
body: <p>I have a fairly new website which allows people to create their own profiles and such. The issue is that when someone links to their profile from their website/blog, their profile shows up in google searches for my website - and to date the <b>one</b> person who has done this has a NSFW profile. Which means, when you search for my site on Google one of the top results is a NSFW page.</p>
  
  <p>How do I prevent google from listing subpages in the results? Would robots.txt solve this? And if a page is <i>already</i> listed, will adding an entry in robots.txt disallowing access to profile pages in general end up removing it from the results?</p>
