Deprecation notice: Removing anonymous gist creation

GitHub is set to deprecate anonymous gist creation in 30 days due to the high volume of spam associated with this feature, despite its utility for quickly sharing code snippets. Although this decision follows considerable deliberation, users can still access existing anonymous gists and are encouraged to create GitHub accounts to continue benefiting from gist creation. The deprecation process will begin on March 19, 2018, at 19:00 UTC, when anonymous gist creation via the web and API will be disabled. Users are advised to refer to the documentation for more information on creating gists.
