This is a great concept and pretty much how I approached online dating when I did it about 10 years ago.
OP, I didn't get any real relationships out of online dating - several dates, a few flings but nothing more. I don't know if I could have done because I was the one saying no to second dates or ending short flings if it wasn't right for me. Can you honestly say that all of these men were right for you? That there were no 'red flags'? Were they all potentially relationship material? I very much doubt it!
People talk about online dating being a numbers game and I suppose it is to an extent but if you are dating lots of men and also feeling rejected by them when it doesnt work out (presumably you reject some too?) Then I'd wonder if you're approaching it with the right attitude. Just because you've matched one dating app and gone on a date, doesn't mean you're what each other is looking for in another person.
You need to make sure your life is full and fulfilling in other ways - work, friends, hobbies and then OLD is just another hobby you pick up when it suits you.
I always think that one of the dangers of OLD is that it lowers your standards somewhat. For some people, 'being in a relationship' is the goal; for others, it's the opportunity to meet different people and work out what their must haves and deal breakers are; for others, they're happy to be selective and keep an open mind and, if they meet someone - great, if not, it doesn't matter because their lives are full already. Some people overlook obvious problems with a person thinking, they were better than some of the others or that they don't want to be too picky and are happy to give someone a chance when they really probably shouldn't.
Your complaint is that they ghost, end it after a few dates or a couple of weeks. But surely you do that too (well, maybe not ghost) because not everyone you go for a coffee with is going to be compatible with you.
And, finally, as others have said, there are some absolute losers doing online dating. There will be some decent men on there but they will also be attractive to lots of women and be able to choose someone who is perfect for them. Be yourself but make sure you are the best version of yourself. Don't be too quick to progress with someone just because they seem interested. Think about whether they're really who you want too.
