It was a nice move. Unfortunately, there's a large gimmick aspect to it. So I don't know if it's something that would net a similar benefit long term or with repeated use.
Not that it matters...
I think it will only be a short time before most nations adopt legislation similar to Korea's "real name verification" anti-anonymity laws. So far, the UK, France, Australia, and the US
have legislation pending that would basically require a license to access and use the Internet.
And with the huge amount of media and entertainment industry lobby money behind the push, (and several government security agencies jockeying for ever bigger roles and budgets) it will only be a matter of time.
