I want a script that can insert many combinations of keyword misspellings on each page, depending on the page's title. I don't know if this can be done with htaccess or php, but the script would have to generate misspellings using rules such as the ones found here [url removed, login to view] Option I would also like, but is not necessary, is the option of dynamically rearranging sentence order and/or replacing with synonyms from a synonyms database the content of each page. The content itself comes from rss feeds and is dynamically generated, so this might be tricky. Nothing between html tags would be replaced, just text that is output on the page. I want to script to be compatible with all the content generators out today such as RSSGM or blogsolution for anyone that is familiar with these, or to be available for use on any site. To recap, need dynamic misspelled keyword insertion on each page depending on the page title. Keywords can be inserted throughout the document once per misspelling, or inserted before the at the end of the page if random insertion isn't possible. Content Rewrite engine is also wanted but not necessary, but it has to be dynamic, as each site has 50,000+ pages, and would take too long to upload each site with the changes.
