Death doesn't kill a digital footprint.
Rodrigo Sanchez-Chavarria knows that all too well. Since his friend William Brandon Lacy Campos, a poet and activist from the Twin Cities, died unexpectedly in November, he has watched Campos' Facebook page become a memorial guest book, where people post heartfelt tributes.
"It's really beautiful to see how many lives he's touched," said Sanchez-Chavarria, who continues to post to Campos' page. "At the same time, it's tough because you never get a message back."
By one estimate, more than 500,000 deceased Americans left behind Facebook profiles in 2012. Grieving family members might find comfort in sharing old stories on Facebook timelines, but it can be jarring to see photos of a dead friend reposted on Facebook months later.
"There's no 'I am dead' button," said Jed Brubaker, a Ph.D. candidate at the University of California-Irvine who studies death and online social networks. In fact, Facebook profiles stay up until someone proves to the social network that the user has died. Often, no one does.
So "friends" might still see birthday notices for the deceased pop up in news feeds or even watch their "likes" appear alongside advertising.
While a funeral comes with expected traditions, grieving online is evolving. With more than 1 billion Facebook users worldwide, more people will be confronted with these lingering digital ghosts and nagged by questions about who controls our online legacies after death.
"There's a lot of anxiety and confusion," said Brubaker, "and some people are just downright upset."
