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 one 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.
How do I prevent google from listing subpages in the results? Would robots.txt solve this? And if a page is already listed, will adding an entry in robots.txt disallowing access to profile pages in general end up removing it from the results?
