Quora 把知识占为己有

昨天分享的文章在唱衰 Quora 。今天这篇,也是在吐槽 Quora 的。 吐槽的点是,Quora 的 robots.txt Internet Archive 的爬虫给屏蔽了。Quora 给出的理由是:
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.
