I dislike the term "forum/blockland Self Delete" to describe these sorts of events.
The large majority of Self Deletes go quietly and unnoticed, by things like hanging yourself in your house, or jumping off a bridge, or drowning yourself in the sea. A few people might unfortunately come to discover the scene, but that's it. Someone on the forums might ask where a user has been, like smelling a rotting scent from next door, and you'll realise they left. That's a Self Delete.
These events are more like walking on live TV and blowing your brains out with a gun, splattering the audience.
It's not taking your own life for your own sake, nor a desperate plea for help. It's just a malicious attack.
Anyway, I don't expect much better from someone who is such a child. Pathetic really. Everyone who 'Self Deletes' like this should just grow a spine.
