<li>70.32.90.172 is on Media Temple and has no user agent</li>

<li>I note that the nginx log shows &lsquo;-&rsquo; for a request with an empty user agent, which would be indistinguishable from a request with a &lsquo;-&rsquo;, for example these were successful:</li>

<li>I can only assume that these requests used a literal &lsquo;-&rsquo; so I will have to add an nginx rule to block those too</li>
