Recently a prominent user in an online community died, and some of the users have come together in various ways to share memories and comfort each other. I'm not involved, but observing it made me wonder how users and leaders in a community can best manage this process at a time when everybody's feeling a little fragile. It's likely that this will, unfortunately, happen to an online community that I am deeply involved in eventually, and I'd like to gain some insight into better or worse ways to handle it.
The community (which I'm deliberately not linking; please let's keep this general) is using a shared chat room. As far as I know no relatives of the deceased are there now, just community users, though it's all public. I've seen some behavior that seems like it could make some community members, and relatives were they to come across it, uncomfortable, including:
Speculation about the cause of death, which wasn't reported. One person went so far as to comment on the person's physical appearance (in a photo) and speculate negatively based on that.
Extended transference -- "this reminds me of this thing that happened to my {friend, relative}...", which seems to deflect the content that people actually came there for.
Comments criticizing people doing the above as insensitive, and ensuing responses.
One approach to this kind of situation is to say that the community members need space to react in their own way, and that trying to steer or moderate this activity is counter-productive. Another approach is to say that it's even more important than usual to steer or moderate such conversations, because of the sensitive nature of the situation. My limited knowledge about comforting mourners applies to in-person situations, not online.
What's the best way to handle online grieving, on a spectrum from "anything goes" to "carefully and sensitively moderated"?
