I'm not sure if this will work yet, but I have faith.
This problem was ultra annoying to our blog so I had to dig in the code of the plugin.
At some point it checks the freshness, I removed the call that updated the post.
Find this line:
elseif (!$this->filtered() and $freshness == 1) :
And under it, just remove everything it does. I've added:
$ret = false;
But I guess that's unecessary. Hell I could've completely deleted the condition.
Hope it helps.
