LastPass edits robots.txt to make support articles difficult to find

  All of today's support bulletins are not easy to find, with none of them listed in search engines, as the company added <meta name="robots" content="noindex"> HTML tags to the document to prevent them from being indexed by search engines.

2) To clarify a bit, afaik, robots.txt is a request / suggestion, a nice to have if you will. It doesn't prevent indexing.
