Sorry but that's also useless until we know whose lives are in danger and who is an obstacle to their lives being in danger.

Because if the motivation is to save lies, why would you keep that information secret?

Maybe you can ask your friends if they have something more precise and more useful that their ego being hurt?

That could be for example "people who have a tendency to do depression are at a higher risk of suicide because Facebook has been optimizing user engagement like a psychopath".

Now yes I would be interested because that looks like an area where you can have a meaningful positive effect in the real world.
