Spot on! That window for entries tells the whole story. If a task is completed that fast, it wasn't a 'challenge' or a creative 'activity'—it was just a claim button. When a single user can drop 6 of these in a day, they aren't contributing to the community; they’re just managing an assembly line. As you said, the term 'activity' is dying because it has been stripped of any actual effort. It’s just high-speed MLX farming now, and it’s pushing real social interaction right off the feed.
