Well, being verified is often a time consuming process (you're ensuring the person making the account is THE Arnold Schwarzenegger not someone claiming to be Arnold Schwarzenegger) so there seem to be questions about how he could do this while also cutting half the workforce? Automating it down to "this person clicked a verification link in their email address" doesn't really mean they're verified in the way it does now because a scammer can use a throwaway email address. The check mark is for the benefit of twitter. It creates a valuable experience for other twitter users to know they're interacting with the real Arnold Schwarzenegger If Schwarzenegger opts not to be on twitter and a scammer impersonates him, scams other twitter users-- that's a problem for twitter, not Schwarzenegger. It will reduce the value of company and drive users away. Fewer users means fewer people they can serve ads to.
