At all timezones, throughout the day ive never seen the player count go above 1k, usually was 800 on offpeak, 1200-1400 peak. Now its like 600 offpeak 900 peak... Ever since that one day when suddenly there was a gross oversupply of petri leechers about 2 weeks ago, and yet another big ws/cs depression after chair gacha + 2x nx the playercount tanked. Its getting extremely hard to find leech buyers.
Usually, the player count rise a lot during major events. Soon as events are over it usually drops quite drastically it seems.
Large number of cheaters got banned at an increasing rate thanks to our hard working Staff. A lot of people went back to focus on school as well. I'm pretty sure the population count will peak again with all the ban evaders sneaking in around Halloween event.
Right now in Asian Countries are at the examination periods! Once the holidays comes it will go back to really active again!
Between after event burn outs, and the start of school for a lot of people, it can get a little scarce. It's also possible with new later game content (CWKPQ/GPQ), and the addition of those HP quests, leeching may become less popular (perhaps that's optimistic).
