 - `spoiler_text`: a map consisting of alternate representations of the `spoiler_text` property with the key being it's mimetype. Currently the only alternate representation supported is `text/plain`
 - `expires_at`: a datetime (iso8601) that states when the post will expire (be deleted automatically), or empty if the post won't expire
