Separation

The Account Is Not the Person

ACCOUNT IDENTITY

  • body
  • consciousness
  • intention
  • authorship
  • presence

Account

  • username

  • timeline
  • followers
  • archive
  • access credentials
  • platform identity

Death ends the person.
It does not automatically end the account.

Identity persisted while authorship changed.

Announcement

The First Post After Death

On August 19, the account announced that Akira Kusaka had died the previous day. The post explicitly stated that it had been written by her family.

An account can become the place where its owner's absence is announced.

Continuity

BEFORE

  • username
  • profile
  • timeline
  • followers
  • author = person

AFTER

  • username
  • profile
  • timeline
  • followers
  • author = family

Unchanged

  • username
  • platform identity
  • archive
  • audience

Changed

  • author
  • intention
  • legal / social ownership context
  • meaning of future posts

The container stayed the same.
The meaning of speech changed.

Afterward

From Account to Memorial

  1. ACCOUNT
  2. ANNOUNCEMENT CHANNEL
  3. ARCHIVE
  4. MEMORIAL?
  • When does an account stop being a personal account?
  • When does it become an archive?
  • Who inherits the right to speak through it?

Inheritance

Who Inherits a Digital Identity?

  • login access
  • account control
  • audience
  • old messages
  • archived posts
  • public identity

A digital identity can survive its original author and become something others must manage.
