Sorry this is tooooo long.
I agree with @deviantsusie. I have raised this enquiry last year with Tight1piece. About how the online status and last online stamps work. I was told it was inconclusive that the last online time may be the start time when they login or begins when they go offline.
My settings:
- "Always show me as offline" is selected
-"Remember Me" is enabled, site is fireproofed so I don't need 2 reauthenticate each time
-I switch VPNs (Proton and Nord) mostly using Proton with smut
-Android OS, Duckduckgo browser
-new tab is opened via bookmarks, tab is closed every after session
It shows "2 hrs ago" whenever I'm online which I understand is the stealth feature of the Platinum. It adds a chat bubble icon when I'm in the Chatroom whether you're in a PM, an actual private/public room, or even simply floating in the Chatroom but not in any room or PM.
Once offline it shows a progressive last online stamp that shows from minutes (if it was under an hour) until it reaches an hour to hours until it reaches a day then in days until it reaches a week to weeks until it teaches a month then months until it reaches 90 days.
I don't remember the last time I saw the login page but my current last online timestamp was reset days ago. I have been switching IPs (Proton VPN) but it's been counting days.
Regardless of the subscription type whether free or any of the premiums including Platinum, the last online/session time (after the user goes offline) varies.
Observed Scenario 1:
User A goes online for 5 mins. When she goes offline it shows she was last online "5 mins ago." She goes offline for 40 mins then back online at 1:45 for 15 mins. When she goes offline again, it shows she was last online "1 hrs ago" which originated from the 1:00 login as if she wasn't back online 15 mins ago.
-iPhone then Windows OS laptop used, no VPN, Chrome browser
Observed Scenario 2:
User B goes online for 5 mins. When she goes offline it shows she was last online "5 mins ago." She goes offline for 40 mins then back online at 1:45 for 15 mins. When she goes offline again, it shows she was last online "15 mins ago" which originated from the 1:45 login.
-Android phone, same IP on VPN, fireproofed site on Duckduckgo
Observed Scenario 3:
User C was last online "20 hours ago". She goes online for 2 hours. Once offline it shows she was last online "22 hours ago". She goes online the next day for a few hours. Once offline it shows she was last online "1 day ago". She goes online daily thereafter and it shows last online "2 days ago", "3 days ago", "4 days ago" and so on as if she wasn't online daily for several minutes to a few hours.
-daily IP switches via VPN, fireproofed site on Duckduckgo, tab used and browser are closed every after session, no reauthentication done, new session via favourited bookmark
Observed Scenario 4:
User D goes to the Chatroom daily but her last online shows it has been a month ago.
-unsubscribed member, no VPN used
