Why are some blog entries and comment modules closed to comments?
All comment modules, whether on blog entries or other webpages, are automatically closed after a period of time to help reduce spamming and off topic discussion. The default duration that modules are open to comments varies. Some modules may also be closed early, for example if the debate has changed, run its natural course, or is no longer topical. The length of time modules are open to comments can likewise be extended, for example if the debate remains topical for an unusually long time. In very rare cases a blog entry may never be opened to comments, for example if a story is so sensitive that commenting would put users or the SmartCityCoin.io at risk.
