Thanks 006, but there was absolutely zero extra effort involved in getting it to work with titles as well as thread bodies. The way the replacements system works, the entire page seems to be fed through the filter before it's sent to the browser, so it's always likely to catch everything. I may be wrong there, but it seems that way.

It could present a problem if a forum used a, image URL or something that matches part of the replaced text - users with the censorship turned on would end up with missing images. =)
