DMOZ Sites gone

I was updating a wikipedia article that linked to the dmoztools.net for a listing of murder mystery games, under party games>Murder mystery games>Downloadable. The problem is that there are zero listings there and my site was listed here in dmoz.org for 15 years along with around 30 other sites. I tried many times over the years to get moved to the root of murder mystery games since we sold both box and download, but they never moved us. There are a few strange things in that root that don't belong, but again, no websites under downloadable. Why would the sites that had been there for so many years just disappear? I get that they are closed, but the mirror should have kept those sites linked.
