I too have no direct experience of this plugin but in order to join the conversation I woukld look at the language encoding and the validity of the html that these autogenerated pages posses. Also are there any autoinserted links in the content that this plugin produces?

1 day seems a little quick for a penalty but if there is garbage html and/or garbage links it could be possible.
