Recent chat about ghosting and the general consensus is it's not a nice thing to do, but I suggested that if I went on a date and l thought 'I really don't like you' it's OK to ignore them if they get in touch. I wouldn't consider this ghosting.
Now if they were a decent enough person just not for me I'd likely either tell them at the end of the evening or decline a 2nd date if the contacted me.
Now going on say 4 dates, having a snog, making all the right noises, THEN ignoring, we'll that's rude and I'd consider that ghosting.
Turning someone down and getting follow up messages eg "is it because I'm too short....you've not really given me a chance....we could go together just as friends" etc I would then ignore.
In my eyes ghosting is when you're being unfair after having toyed with their emotions.
