This is a very unpolished patch, which basically checks all input against a blacklist file of prohibited patterns to help block wiki spam.#
See also SpamFilter.
I hope to enhance it and package it better in the future. One very important goal is the ability to reload the blacklist file without restarting the webapp.
To use this: get the source from CVS. Add the java file. Apply the patches. Build it. Then configure & deploy like normal. Add jspwiki.TextContentVerifier.enabled = true to jspwiki.properties. A sample blacklist file is attached; put it in WEB-INF right next to jspwiki.properties
Please let me know of any suggestions and improvements. Improve it yourself if you want!

Question: Dave, why didn't you tie it to the PageFilter system?
Janne, if I understand correctly, PageFilters modify the display of pages. This checks the text before saving the changes at all --DaveBrondsema
The SpamFilter throws a RedirectException upon save, if a page is deemed not worthy. PageFilters can be used to modify or reject a page on saving as well. --JanneJalkanen
But does it actually work? For instance, if I were to put in something like http://www.vegasonlinesports.com NFL Football Betting, will this be blocked out partially, or entirely?
Thanks
In this case, if the poster is not logged in, you could add a check_poster_is_human step, like YahooGroup does ("enter the text you see in the image").
Obviously, it would only stop automated spammers. --AlainRavet
Yes, it works. If the user enters something that matches a prohibited pattern, an error message explaining that will appear and the new version page will not be saved at all. --DaveBrondsema
