Yes, I think this is critical. When you are fighting bots, you can't let the bots vote. Democracy Earth and other online democracy groups are looking at ways of identity validation via Blockchain — you should look into these solutions, and choose ONE (or at least a non-overlapping set of providers). See their white paper:

On a different, but equally important note, I'm working with the Democracy Earth people on a canonical debate solution that has similar goals, but with a very different approach.

Let me know if you see an opportunity to collaborate!
