So is your argument that this particular person, Ban Tran, is not noteworthy enough and therefore not worth tracking down for a documentary about women in videogames?

What part of the article in particular do you think puts "the bar really low"? I don't see it. It seems respectful and not at all intrusive, well within the subject matter and not including extraneous or irrelevant personal information.

That's not what I meant. I meant tracking down is ok, but not public search. I think it is a privacy invasion, but famous/very noteworthy person have to bear with it (at least that's normally what society agreed about), but normal people at least shd be protected from that.

I meant her involvement in the video industry does not justify such privacy invasion.

By virtue of what she accomplished, she is noteworthy. If she is found and expresses no wish to communicate on the topic, then it would become harassment.
