Is that tweet from a human? N.J. lawmaker wants bots to identify themselves, but experts have concerns.

"One of the most concrete examples is the potential unmasking of anonymous accounts, said Ryan Calo, a law professor at the University of Washington whose work on emerging technologies includes a paper this year examining bot disclosure issues.

“So while on its face it doesn’t require someone to say who they are, as enforced it has that potential, and it creates a tool to unmask people just by calling them bots,” Calo said."
