Yes, I don’t expect him to answer, even though just naming a city where you lived or have lived before is not doxxing yourself, it is personal information that I understand someone not wanting to share.

That being said, his claim was that his city had most of a list of things, you can’t make that claim and not expect to divulge the city, he could have hidden the fact that it was where he lived or had lived before by saying “X city has most of that” which would have allowed him to give verifiable information about his claim without doxxing themselves. But as it is it sounds like the person who swears he has a girlfriend who lives in another country and has natural blue hair, but no one has ever seen her.
