The Closedverse Leaderboard (alternatively the CV Leaderboard) is a list of Closedverse users sorted by their follower count compiled by the former clone user fanficc (otherwise known as nice >:]). The leaderboards extracted the data using a bot that sampled 10,000 random posts in order to compile a list of over 1200 users. Users whose posts were not featured in the sample would not be on the leaderboard.
The first rendition of the leaderboard was posted to Closedverse on January 22, 2018. Another leaderboard was posted on January 24, 2018, during which Arian's account was hidden and thus excluded from the list. fanficc also put the different renditions of the leaderboard as pastebins:
Closedverse Leaderboard 1/22/18
CV Leaderboard Slightly revised edition (January 23)
CV Leaderboard revision 3 - Arian is hidden edition (January 24)
CV Leaderboard revision 6 - Look at Crispy Go Edition (January 28)
(The fourth and fifth revisions of the leaderboard could not be found.)
