@CallmePaul it is a challenge when you have to basically believe a stranger - what they/we say about ourselves. It is bound to be the best parts rather than why some are single eg emotionally immature, infidelity, lazy, misogyny, broke, scammer/catfisher (long list).
It is a shark pool and as long as you go into it aware and prepared, you can succeed. The App being a commercial enterprise tells us that people (we) are prepared to pay and take a chance to find our "someone" because our day to day life doesnt bring is into contact with a potential beau/belle.
It isnt about me but, for example, have had many OLD first dates, turning into a handful of possibles. 3 of those turned into relationships.
It came to light one struggled with bipolar and chronic moneypinching to the point of nevet even buying a coffee.
Another was longer distance and was single due to lack lustre effort. He prioritised football and friends. That is fine (for him) but not what I signed up for (to date a confirmed batchelor).
Last one was the long game. Funny, charming, easy on the eye. Always wanting to borrow money. He is back on the apps (he used them like a pin ball machine except his wins were s3x and chance to "borrow and bolt" with someone's cash).
My point of the above is not one of them said those things in their profile. It was my task to keep safe and find out. It hasnt put me off but it is about timing and not investing too much emotionally. OLD can be fake or flakey but it can also work out.
Long explaination but hope it gives context and helps your understanding.
