Hello Deepak, The queries you have related to GitHub [1], a company that provides hosting for software development version control rather than Git [2], which is a version control system. It's a rather common mistake. As for the answer to your questions: 1. Yes, but I cannot find any relevant resources for it. Revoking access does not alter commit history and your email should still be visible, thereby GitHub could show the username and contributions. 2. Yes, as per the criteria detailed on Github's help page. [3] Please redirect any further queries to the Github community and support.
