Any GHOSTERS among us? Why do they do it... (Is it a power trip?)

I'm sure both men and women have been there, though I wonder what the proportions are... It's such a ridiculous thing to do, but maybe that's from someone, i.e., me, who doesn't go out of my way to about just wantomly hurting someone. Why do people ghost? What's in it for the ghoster? Whatdya think, eh, people of SW? (asking for a friend!)
