Threadiverse communities differ from following hashtags by having moderators who can remove posts or ban users. That provides extra value because that means people can’t post spam or off-topic things in them as long as the mods are doing their jobs. But if that isn’t possible, then why not just follow a hashtag and post to it?
Same feeling here.
