Usually discord ignores all issues related to invisibility leaks but responds very fast to other types of issues which is why i decided not to wait for weeks for a fix, instead publish it and watch it get fixed.

Incorrect. "Invisible" is a privacy control, not just a UI filter. While the official client freezes the text, the backend still broadcasts live last_logon and last_logoff Unix timestamps in the ClientPersonaState packet. This leaks exact real-time sleep/wake cycles via the socket, completely bypassing the privacy toggle.

In this context, 'Logoff' triggers whenever the socket disconnects. So every time you shut down your PC or put it to sleep, that timestamp is updated and broadcast, even if you never explicitly clicked 'Sign Out'.

Exactly. The 'Offline' feature exists specifically to set that boundary, and the backend completely ignores it.

Privacy shouldn't require leaving your PC running 24/7.

True, but a tracking pixel is an active attack that leaves a visible trail. This leak is passive surveillance; I can silently graph the sleep cycles of 200 friends without ever interacting with them. Trust shouldn't imply consent for invisible, automated logging.
