Last Seen: Unknown

The internet records when we stopped speaking, not what happened after.

We know when someone stopped posting.

We usually don't know why.

Distinction

Inactive Is a Platform Status

Inactive is not a human condition.
It is a platform status.

Platform can see

last post
last login
account status
deletion
suspension
recent activity

Platform cannot know

why they left
whether they remember the account
whether they changed identity
what happened in their offline life
whether they are still alive

Between the last post and the present is a period the platform cannot describe.

The interface preserves the endpoint.
Human life continues outside it.

The internet records when we stopped speaking.
It does not reliably record what happened after.

Meaning

What Does “Last Seen” Actually Mean?

Left the platform?
Lost the password?
Changed accounts?
Changed names?
Stopped using the internet?
Grew old?
Died?

The platform cannot tell the difference.

Social remains

After activity stops, relationship traces can remain.

A person can disappear from activity while remaining embedded in a social graph.

Before the internet can distinguish the living from the dead, it must first distinguish absence from inactivity. It usually cannot.
