I came across a question while I was browsing the main section of Arqade which was classified as a highly active question: Why are pokemon stacked on top of each other whenever I start?
I am a little confused as to why this is a highly active question when it only has one answer, was asked 4 years ago, and seemingly has had no action (besides the fact that it is active today) since 2016. A similar question with even more views and answers, although it is a little older, is not classified as an highly active question: What is the optimal grid?
So why is the first one a highly active question while the second one is not? And why are some questions, seemingly randomly marked as 'highly active' while others, which have even more views and answers, are not?
