WordPress.com don’t get the Principle of least privilege

I just went to post a comment on a WordPress.com hosted blog. I was going to use my Twitter account to log in, and in order to authenticate with my Twitter I was asked to allow WordPress to:

  • Read Tweets from your timeline.
  • See who you follow, and follow new people.
  • Update your profile.
  • Post Tweets for you.

This appears to be because the same authentication is used when you are a blog author and wish to allow WordPress to “Tweet your WordPress.com posts.”.

Come on WordPress. Surely you’ve got the resources and savvy to provide different levels of authentication for bloggers and for commenters? As a commenter identity is the only issue, and the authentication process should ask for no rights whatsoever, beyond being able to read my email address and name. Cf the Principle of least privilege. Lame.
