Alexa 'Claim your site' has been retired.

• This is a question about using the theme.
• This is a feature request.
• [x ] I believe this to be a bug with the theme.
  • I have updated all gems with bundle update.
  • I have tested locally with bundle exec jekyll build.

Alexa.com no longer allow sites to be verified (http://www.alexa.com/siteowners/claim) and is now a paid-for service. I suggest the documentation/feature for this can be removed:
https://mmistakes.github.io/minimal-mistakes/docs/configuration/

Yeah, think this is safe to remove as a feature.
