This is not an unintended feature - it is a gaping privacy gap. That data is not intended to be public, and is in fact dangerous when made public. It's _especially_ creepy that this detailed data is available to someone who has unsuccessfully interacted with you on a dating website.

There was no real-world case where this data was useful in a non-creepy way.
