Please note: anyone with a t.co shortened link will be able to navigate to the destination URL. It's useful to know whether your user's screens have such capabilities, so you can build your site accordingly. An auth token is not necessary for expand requests.
At the top of the post creation area where you are working on your draft, you can change the slug. Set a custom 404 URL so both search engines and visitors are sent to valid pages on my site when trying to follow any link that doesn't exist. See if you are using Classic Analytics (ga.js) or Universal Analytics (analytics.js).
