Why did the journalist search out the real name which is clearly difficult and then not talk to his interviewee about his name being released; because he knew it was immoral.

Your morality is not relevant to good journalism.

It's actually not. People in general like "good stories" and will read and share them more. Adding "credibility" will drive the perception as a "good" story and therefore to some degree clicks as well.

Depends on who's clicking and who the advertisers are.
