To this day I have no clue what the point of this idea is. Forcing you to use an ID on the internet is the real world equivalent of making everyone you interact with take a photo of your ID. It's completely nonsensical.

Considering that most crimes require people to be physically present at the crime scene, it also doesn't seem to be a functioning deterrent at all in the real world.

Most of the bad behaviour is concentrated in "seedy" places, where you usually have to go out of your way to interact with that place. A real name policy doesn't change the nature of the place at all.

If anything, the places that would be most affected are the ones where people are roleplaying or pretending to be something other than "themselves". E.g. gay or transgender people, furries, MMO/MUD/MUSH players, streamers, etc which overall seem to be exceedingly harmless.

There is also the blatantly obvious problem that this only works on people who are risk averse to begin with. So it will basically have no effect on actual perpetrators, who see some risk vs reward tradeoff for their bad behaviour.
