RTFM is mostly a flex that people who got help before you are now referring to because they are already on the boat.

That said, a rudimentary Web search or maybe a llm question, might be in order before asking. You also learn more when you get those little successes by yourself.

You are right that it was a loaded question, and you had a smart answer, but the implication of this “inconsequential” change represented by the current birthdate is of course more invasive identification later.

Otherwise why would they bother, because as it is now it is useless or inconsequential.
