Many men don't want to give personal details, they want to remain as anonymous as possible and not be discriminated against. They also want no pressure, no strings.
Simple as that.
Also how do you know they will tell the truth? What are you going to do if they turn up and you think they are a different age, or something else? Waste your own time?
Actually I get a bit of that when I ask/advise about my drug & alcohol / don't want to see anyone who's hungover but that's something they can control, which is why I can apply it.
This has happened twice to me, both times I saw them out the window coming and simply didn?t answer the door.
The first one lied about his race, the second clearly lied about his age. They knocked and knocked and I didn?t answer. Once they were gone I sent them a text explaining that I don?t appreciate liars and I don?t appreciate boundary pushers who don?t respect my restrictions.
It won?t be my time wasted, since I would?ve dodged a bullet. They will have wasted their own time booking a girl who doesn?t see them, travelling and hoping I change my mind at the door, which didn?t happen.
I state my restrictions clearly on my profile so anyone who tries to trick me will get a wasted journey and will go home pissed off with blue balls.
