How should society handle the need for pseudonyms for privacy without getting too authoritarian?

Especially when you have horrid news like [this sociopath](https://www.theguardian.com/society/2022/mar/30/11-years-10-arrests-at-least-62-women-how-did-britains-worst-cyberstalker-evade-justice-for-so-long) which is creepy AF ; he impersonated people etc. and this story was news last month in the UK but is now no longer in the news.

Pseudonyms do have a time and a place, especially for privacy, but incidents like this will certainly get some people to demand real names for everything which obviously doesn't work as people think; but of course, society is not all clear-cut black and white.

clear course demand everything incidents names people privacy real society work
