+   create a filter using IFDB's

+   For instance, to hide games in a certain language, games in a 
+   certain genre, and games with a certain tag, you can type
+   <br><b>-language:example -genre:example -tag:example</b><br>
+   (replacing "example" with the name of the language, genre, or tag). 
+   While you are logged in, your saved filter will automatically be 
+   be added to the end of your search terms when you search for games.
+   The filter will also be applied when you browse games on the browse 
+   page. At the bottom of the page of results, there will be an option 
+   to search again without the filter. (Note: Game information on IFDB
