Last winter on a 'Zoom date' one match multi-tasked while I was trying to talk with her. She was literally shopping.
Another 'left the chat' after I said I wasn't a property developer, I was a software developer. I hesitate to even mention this because it practically reveals my identity to friends who know that story.
I've met women who chatted for a while, and setup a date, only to finally reveal at the 11th hour that they are seeing someone. Sorry! I've also met women who used very, very misleading photographs in their profiles.
I've had 'matches' who return curt answers to very simple conversational questions, as if how dare you attempt to grace their presence with your messages. I'd take a non-reply over that sort of signal. I would not be texting them in the first place if they hadn't also swiped right on me.
My real life experiences dating someone from Meetup/College/Work had substantially more honesty and humanity. In online dating, I truly feel there's a loss of treating others like human beings instead of a disposable item. And to be fair, I am guilty of that sin as well.
But for all the talk I've heard from my female friends about how guys are awful on online dating (and I believe it), I can assure you that it's not any easier on this side.
