These are the activity statistics for the four main channels in BDI:

Monthly Stats:

Monthly stats are run on over a 30 day period every Sunday afternoon by Nymphetamine, give or take.

Yearly Stats:

Yearly stats are collected from January 1st to the last Saturday of every week right after monthly stats are run. They have been restarted for 2018.

2018 Stats:

The 2018 stats collected from January 1st to December  31st, 2018. (There are a couple of days of outages due to the bot being offline, or disk space full, but are otherwise mostly complete.)

2017 Stats:

The 2017 stats collected from January 1st to December 31st, 2017. (There were a couple of days where the bot was offline and incomplete, but otherwise, these stats are complete.)

All logs are taken from the Murphy bot. All times are Pacific Standard (-8 GMT).
