Knyte is partially retired, I believe, so I don't think you'll get an answer from him. DanWL is the next best for this kind of data, so yeah, listen to him ^^

I assume spam accounts are counted?

Not that it matters, I was just reminded by spamming for some reason.

If anything, spamming could artificially inflate people's views of how active the forums are.

I think all spammers should be banned permanently, as tricking people into thinking the forums are fast-paced is wrong.

@Bane There's over 70 spam accounts included. There are also some accounts that are deleted-from being invited but declining the invite. The first 4500ish player IDs don't exist, so I didn't include them.

@Shread I can't get the data automatically, but I can get it effectively in a couple of hours when I'm not busy.

@Nauzhror

The number comes from player ID-s. Like DanWL calculates them. I am just lazy enough not to find the latest registered player. Then compare it to first registered player - Fizzer.

Games per day solely is not exactly better estimate. If this would be juxtaposed with accounts created daily, then you could get quite good activity data. But again none of it tells you how many are there daily/weekly players and so on.
I have no idea how to collect data on games activity effectively, but if someone has data of games created per month I´d be interested in it. But all declined, deleted, unfilled games have also ID-s which makes them false on statistics.

^ I can only get accounts created, not active accounts.
