That's fine that you have this opinion, but I honestly don't think this is a factor that would stop most people. People on HN have a much different perspective on personal data then most people in the real world. And for companies it not really an issue either.
And I'm sure many large company, politicians and so on would have gone threw the verification process.
Of course now maybe some people wouldn't anymore but when he took over twitter announcing that as a policy seem reasonable.
