Reminds me of an article about Quora and their attitude towards The Internet Archive. quora.com/robots.txt
# People share a lot of sensitive material on Quora - controversial political
# views, workplace gossip and compensation, and negative opinions held of
# companies. Over many years, as they change jobs or change their views, it is
# important that they can delete or anonymize their previously-written answers.
# We opt out of the wayback machine because inclusion would allow people to
# discover the identity of authors who had written sensitive answers publicly and
# later had made them anonymous, and because it would prevent authors from being
# able to remove their content from the internet if they change their mind about
# publishing it. As far as we can tell, there is no way for sites to selectively
# programmatically remove content from the archive and so this is the only way
# for us to protect writers. If they open up an API where we can remove content
# from the archive when authors remove it from Quora, but leave the rest of the
# content archived, we would be happy to opt back in. See the page here:
# Meanwhile, if you are looking for an older version of any content on Quora, we
# have full edit history tracked and accessible in product (with the exception of
# content that has been removed by the author). You can generally access this by
# clicking on timestamps, or by appending "/log" to the URL of any content page.
# For any questions or feedback about this please email email@example.com.
Because adding a line to your robots.txt is totally going to make mirroring the site impossible.
