-   This plugin blocks any contribution that contains chinese characters
-   (as HTML entities). This is not meant to be impolite or discriminate
-   Chinese, but because there are a few very aggressive web/link spammers
-   this is currently the best workaround for primarily English sites.
-   
-   IMPORTANT: this plugin must be loaded together with (before) the 
-   'fragments/head/meta.php' code snippets.
