It’s a simple question without a simple answer, unless you’re willing to accept “it depends” as a simple answer. The result depends upon what you friends and family decide to request and perhaps even what instructions you leave behind. Let’s go through Facebook’s policy and explore all of the options:
Memorialize the profile
Facebook recognizes the importance that a profile can play in remembering departed friends and family. Via a form in its help section, Facebook accepts requests to place accounts in a memorialized state. Once the request is approved by Facebook the account’s privacy is restricted to friends only and certain sensitive information is removed. The profile and wall remain active for friends to post memories and condolences.
