You can write a backend script (maybe a cron job using the FB PHP-SDK) that runs as the special user and makes the desired FB api calls. For this, you will want to use a long-lived access token, which needs to be renewed every 60 days. You might also try your FB api calls using an App Access Token, which do not expire but also do not support all FB publishing and other operations.
