I was trying to figure out how you got those numbers, then I went to https://the-federation.info/platform/73, sorting by number of accounts vs. active accounts. I was astonished how some sites had 30k accounts and 3 active users. Kind of sad seeing the active user ratio going from over 1 in 6 (very active) to 1 in 30 (around where it was before) in the span of 5 days.
