Social Media is more like the old newspaper "Letters To The Editor" than it is like the post office or phone system. On social media, you send your "post" to the S.M. company, the company reads it and decides whether or not to accept that "post" and then some time later, they publish it to the site's readers. The review process is done by a computer instead of an Editor, and takes no time at all (measured in milliseconds) but that's what's happening under the hood. They are absolutely curating and deciding what to display and what not to.
