Yes, I have quite recently (in the past couple of years) ghosted someone. Let's call her 'Eve.'
Thought she was OK to start with, but after a few months, she turned out to be angsty, moany, self-centred, nosey, boring, demanding, irritating, flaky, and pushy. Her husband was an annoying, lazy, rude, self-centred, sycophant (to people he thought would advance him in life,) and he was also flaky. They were also both users. And we had nothing in common. We just kind of floated together because we moved into this village at the same time (us a few weeks before them...)
Me and my DH started to give them a wide berth about 8-10 months after we met them. He got the hint quickly and floated away, but she kept pushing and pushing, asking me (and everyone we knew,) what was wrong and if I was OK, coz she couldn't BEAR to be 'rejected.'
'Eve' got on my fanny SO much that I ended up dropping 2 hobby groups in the village that I went to - coz all I got from people there was' Eve' says she hasn't heard from you, are you OK?' Nothing about me or my family, (how are you? How is your family?) It was just always about her... 
So I quit the 2 hobby groups, pretended I had got a new full time job (when I was part time before,) and drifted away gradually, and ignored her texts, and avoided her in public.
I don't care. I'm not sorry. I don't feel guilty. I can't bear the fucking sight of her face. She stressed me out and got me down, and spending even 10 minutes with her was incredibly draining. She literally gave me a headache when I was with her. She hasn't contacted me for 3 or 4 months now. Thank FUCK. Looks like she finally took the hint. I am glad to be rid of her.
Some people say it's horrible and cowardly blah blah blah, but what else can you do? Say 'I don't like you anymore, you're boring, you're irritating, I hate the sight of your face, will you just fuck off?!'
Coz I don't believe ANYone says that. I do believe that most people will ghost people, and hope they take the hint. No matter what anyone says!
