That's really interesting! I guess I could see folks wanting to treat something like Facebook as a diary/journal of sorts. Just as a person might leave their personal diaries to a particular relative or friend, there are probably folks out there who would like their profile to live on. There are also probably legalities about who "owns" the content on those pages too - I could see a social media site possibly using the photos and stories posted by someone who's deceased. Remember the uproar when FB said Instagram photos would be considered public domain? What protection of privacy is there for someone who's dead?... To answer the OP, I know of several people who have passed, whose profiles are still on FB. Mostly they seem to remain open and friends post their memories of the person - sometimes going there to express how much they miss the person - almost as if the deceased is still checking in. As a high school teacher, I see this especially among the friends of students who have died under tragic circumstances - car crashes, one former student was murdered, etc.
