Yes, I've seen this, and it annoys me. I think people should treat others with respect; discomfort with difficult conversations ("it's not you it's me" etc.) doesn't absolve us from the responsibility to treat people with care. I've not "ghosted" (and been thanked for being honest) but it's happened to me a couple times. That does sting. (Not counting going on one date with someone and neither feels a spark and neither follows up - I think that's okay, you are only meeting someone and not involved yet.)
"Whether this behavior has become more predominant with the advent of technology is debatable, but perhaps now it stings more, since there are so many ways to see your beloved interacting with other people while ignoring you. The rise of apps like Tinder and Grindr, and the impression they give that there is always someone else — literally — around the corner, is certainly empowering to ghosts."
