If Digg is about "Handmade by human hands" should it do more to verify you are human?

Might be a controversial post, but one of the downsides of other spaces has been the dominance of AI bots and the uncertainty of whether you are engaging with a real person.

I like how Digg has a "About OP" focus when you click on a post. Maybe add ways to get badges that validate your authenticity. However.... the best way I can think of is through face recognition.
