>>28532274Techniques to estimate membership:
1. Scrape unique members who chat in any stream over a period no longer than 30d.
2. Member post or video likes or votes over a period of no longer than 30d.
3. YouTube emote slots, inaccurate because most Hololive vtubers aren't using their cap, they almost all have the maximum of 5200+ members. For example Kiara has the maximum emotes used and says she can ask YT for more, so she has at least 5200 and more if she's confident in exceeding the cap.
4. Member stream viewership bug by adding a member stream to a playlist on iPhone. Only a small portion of members catch a stream live.
These together will form the membership floor, the minimum number of members each vtuber could have, but nowhere near their actual numbers. The few people who have scraped chat over the years have shown that Gura's membership exceeds everyone else by more than double.
Can't count on views as they can repeat, can't look at a period longer than 30d or else you count lapsed members, and even 30d is suspect and shorter periods would be more accurate.
