Well, I submit that the real challenge is to actually detect consumption. Botting began in games, back in the '90s, and many games yet have problems with this. @drugwars has recently banned many accounts for exactly that. Simple scripts can point computers at content, and no one would be the wiser without some means of differentiating those scripts from actual eyeballs.

Until you solve this problem, all you can do is enable bots to be profitable posing as people, and most dApps will be well aware of this. They won't want to pay for bogus views.
