The wordfilter module allows you to filter words or phrases in site content and replace the filtered words or phrases with specified replacement words or phrases. The text body of node and comments are filtered and optionally the title of nodes and subject of comments are filtered. The filters are applied on content viewing so the original text of your content is not altered.
