When things like this happen I always think that the more important problem is the fact that he chose suicide. This sort of thing cannot be gotten rid of entirely. It's impossible. They can always be lured into another messaging system that doesn't track or analyze data at all.

I know this would be extremely embarrassing but it is far from life destroying (or at least it should be). Within a year life would've moved on and no one would even care. We all need to better come to terms with this reality and neutralize its impact and the shame of it.
