It looks like funding all those sock puppets with coin would cost lots of money.<p>From the slides:<p><pre><code>  Sending 10 points to someone would require 10 addresses
  with at least 2 points each. Creating 10 addresses with
  2 points each would require 10 transactions of 4 points
  each, meaning 40 points.
</code></pre>
Those 10 addresses require the same funding amount whether from sock puppet accounts or from one account.<p>Perhaps it&#x27;s not exponential though.
