It's not exactly the same as what you're asking about, but still, in the
March 9th updates of new function Dai-kun stated

More Social Group Options
This functionality has been extended with new group options including:
* Enable/disable images
* Enable/disable messages
* 'Users must join to see content' now completely hides content including image thumbnails |
Yet it doesn't seem like the 'Users must join to see content' feature works
Since everybody can still see every group's discussions without joining, so it might be a bug maybe? At least it was intended to be invisible from other users at that point, maybe it was turned off later or something but either way, I think the 'Users must join to see content' was a really great idea and hope it gets fixed or comes back even for unmoderated groups
