Cloud and engagement farming
We reaching a point in tech side of things and social media presence that people are pretty much hypnotized by social media and therefore their value as a person in their mind/world is dictated by the likes and followers they get in the digital realm.
So it makes sense that when even a negative event is happening their first instinct is to always pull out their phone and start snapping pictures or record a video, merely because they think of all the likes and engagements they are going to get from it, but I'm sure there are some smaller percentage of people which getting engagement is not the first thing that comes to their mind when such events happen so not denying that either.
