world4ch uses it, and I think I was using it until I noticed that nobody posted to it.

world4ch is still running, and I think the only applied patch fixes a bug where appending the banned notice to a post reset its date to 1969. Of course, it does use an older version, but even if the newer one is buggier it's probably less work to fix it than restart on your own.

Not quite the same situation, but http://www.joelonsoftware.com/articles/fog0000000069.html
