title: Are git emails of authors in commits publicly readable?
body: <p>I noticed that in my commits to github there is my email address.</p>
  
  <p>I couldn't find this email address appear anywhere on github, but I was wondering if it could appear anywhere and be crawled by bots for spam?</p>
  
  <p>If so, is that possible to remove the email address and not have it in the commits anymore?</p>
  
  <p>Note: the project is open and public on github (not private repository)</p>
