Our company at present is in charge of production of the following campaign site. （http://www.sanyobussan.co.jp/products/slot_warausalesman/quiz_cp/）
This site is equipped with a quiz, and the participants of the campaign are invited to take it and submit their answers (the answers are to be submitted using twitter as tweets). The system is set up so that the twitter account of our campaign site (@sanyobussan) is automatically followed by those who submitted their replies, but relatively frequently (in about 30 percent of the cases) people who submitted their replies are not made to automatically follow the site's account. Specifically, the system of posting the replies and the automatic following works with the following flow. 1) User accesses the page 2) Simultaneously with access, the session ($_SESSION['screen_name'], $_SESSION['oauth_token'], $_SESSION['oauth_token_secret'];) is checked. 3) If the session exists, a check is made whether the user is following our account or not. 4) "Post a reply" button > oAuth authentication > Session information is written onto the call-back page, and the user is redirected to the source page. 5) (Redirection) 1-3 are executed again. 6) The user is requested to post his reply on Twitter, and if in step 3) information returns that the user is not following our account, a request to follow it is sent. I believe that the automatic follow system is quite common, and would like to know your opinion about what kind of causes could result in the situation as one described above where follow does not work. -- Twitter developer documentation and resources: https://dev.twitter.com/doc API updates via Twitter: https://twitter.com/twitterapi Issues/Enhancements Tracker: https://code.google.com/p/twitter-api/issues/list Change your membership to this group: https://groups.google.com/forum/#!forum/twitter-development-talk
