Seems like 7994.49 is the average posts per day, however that seems hard to believe, and I would say its much more than that.
Like as you stated, the data is not up to date. It's limited to December 13, 2017. So, the avg is correct for that period, IMO, since at the beginning, there was less people.
In mid 2017, the ratio of posts have been increased significantly. Therefore, if we take the data of 2018, the data will be drastically changed.
We're now at 31k posts per day, which was 50k posts per day before the changes.
If you check
patrol, you'll see it's still mostly useless spam.
Does this list count the deleted posts too? Or only posts without the archival.
