Ahh. I see. I took a look at the script. "Blocked Users," is not reported by an instance, but rather It's calculated by this script by looking at "Blocked Instances," which is reported. How many active users each blocked instance has and then summing this together, the script shows "BU." I was thinking it was an explicit list of users the instance blocked based on ban/block lists.
It's a derivative, but still useful metric, I guess. BU could be high, but BI could be low and vice-versa.
You understand that global economic stability relies on people gambling their lives on a dream, right? Well, that and pure willful ignorance.
What would the journalists do? Try to explain that to people, and that nobody has figured out a way to fix it yet?
