The actual data sent to Google when you block a domain does not contain the search query (or the referrer).<p>This is what gets sent when you block a domain:<p><pre><code>  http://www.google.com/gen_204?atyp=i&oi=site_blocker&ct=addToBlocklist&ei=[CSRF-cookie]&cad=mattcutts.com
</code></pre>
and unblock:<p><pre><code>  http://www.google.com/gen_204?atyp=i&oi=site_blocker&ct=deleteFromBlocklist&ei=undefined&cad=mattcutts.com
</code></pre>
(Interestingly the CSRF token is broken when unblocking.)
