-   The page "BannedLinks" can hold URLs (or domain name / link patterns,
-   if put into square brackets) which will be filtered from the Wiki
-   everytime someone tries to put them on a page.
-   Filtering uses Google or a special redirection page to decrease
-   search engine ranking.
-   
-   - use this plugin if you encounter consecutive spam injection; it
-     is the preferred/recommended method
-   - plugins/linking/zero_pagerank.php is however more accurate and
-     up-to-date with banned URLs, as it operates at rendering time
-     (but therefore was also slower)
