- According to Coin-1's newbie rank-up thread, 4289 newbies received their first merit and became Jr. Members between September 17 - November 9. This includes the massive boost after the 1 merit requirement for Jr. Member rank was introduced. ~500 Jr. Members have been banned during that time period.
Thank you for mentioning my thread. I will keep it updated.

My analysis also uses the list of permanently banned users. To be honest, I look at the BPIP service made by
Vod and then I
manually add such users to the corresponding list. Undoubtedly, I need to make a modlog parser in the future.
