You've used an analogy instead of an example to demonstrate your point: analogies can be helpful for explaining concepts but are rarely accurate enough to prove logical parity.

It would be much easier to discuss the merits of your argument if you had an example of the dangers of leaking creation timestamps for database entries.

Otherwise, carparks & database creation timestamps have nothing in common that is meaningfully relevant to your argument. You cannot just generalise all worldly concepts & call it a day.

The other post literally mentions using creation timestamps to judge growth rates of companies on a platform.

My analogy was meant for a reader with a modicum of ability to connect dots to better interpret the parent and aunt/uncle replies.
