Online in what sense?
It's a mystery to me:
LoyceBot often scrapes pages, but it's still stuck at only 14 days logged in. I've tested an auto-refresh in the past on my main account (when someone was checking my online time), and that made my time logged in go up real-time.
Recently, there was a topic about a few users in
Bitcoin Forum - Statistics Center, who's "Most Time Online" increases a couple dozen times faster than real-time.
I just tested it.
I refreshed a page using my account
Then I visited my profile using a device which wasn't logged in. I refreshed the page every minutes. After 18 minutes my status changed to "offline"
Then I refreshed a page again using my account. "The total time logged in" didn't change.
Then I refreshed a page using my account after 3 minutes. "The total time logged in" increased by 3 minutes.
So, the system is working fine for me and I guess it's working fine for almost all of the users.
"Total time logged in" increases as long as the time difference between two consecutive activities of the user is less than x.But you are right. I am sure there is a bug. All those accounts listed on top 10 of "Most Time Online" have been online more than the time they've been a member of forum.
All of them except the first one have registered on August 2018.
Edit: Found the bug, posted a new topic.
