Twitter can fix this with an existing feature that has perceived value to the user base: Open up being a "Verified User" to anyone who uses a real name (or otherwise proves a real identity). Then, allow all users to filter notifications/replies/viewable tweets by whether or not someone is verified. It doesn't remove the option to be anonymous, but others can limit their interaction with anons if they choose. (They could even charge for verification I suppose.)

I'm sure plenty of "regular" people (i.e. non-celebrities) would verify themselves for the blue check mark. To date it's been reserved for select users and gained a value on Twitter. They could capitalize on that here very easily.

E: typo.

I imagine they would want separate tiers to deal with collisions. "Yes this is my name" is different from "yes I am that well known person." In short, you'd still want to distinguish between a famous no-talent ass-clown and a random office worker of the same name.

(And I'll admit it, I mainly posted this comment so I could make the Office Space joke.)
