This was always a major issue when I worked closely with the Dept for Education, namely everything was stipulated as having a budget that ran to Date X exactly but there was an insistence that there be a digital aspect to everything that could function as a "legacy" for the project with no concept that systems need administration/hosting/support/backups/etc. Now I am not saying that the blame is singularly with the Dept or with suppliers, just that neither fully understood that the digital offering had to either augment an ongoing human business process, or an ongoing human business process had to have ownership of the digital offering in an ongoing capacity. This is pretty much an unsolvable problem when you address the other issue that funding is always cut at Date X. In this case though I assume funding is ongoing so it's a case of no one being assigned ownership of moderation (or rather ongoing moderation was not a primary concern of their goal).
