It’s not exactly easy to tell if someone is who they say they are on Vine, Twitter’s new video-sharing app. Case in point: There’s an account with the username Vine. Who is it? Hard to tell — maybe it’s run by the company; maybe it’s an unknown, opportunistic individual.

Duplicate usernames and easily faked profiles mean it’s difficult to ascertain the legitimacy of high-profile Viners (if that’s what we’re calling them). For now, our best way to tell who’s who on Vine is if verified Twitter accounts plug their six-second videos, or if they pop up when you look for people to follow via connected Twitter accounts
