Why is this post grey?
This is not including the important and elusive count of true influence. The basic ways are usually like/bookmark, repost, replies/comments. An overlap can also be if your posts get referenced outside the social media network a lot too.
Counting a couple thousand followers as categorization is meaningless since they could be barely interacting to really interacting. And at such a small follower count, low interaction could mean someone with a couple hundred followers is more of an influencer in terms of literal influence than someone with 10x followers.
