Not sure what makes The Wired underground ...

And if the person running it is having trouble paying for hosting (https://wired.jocadbz.xyz/comments.html?postId=32), I have to wonder about the viability of the site.

This looks more like a home-grown chan site. Probably a better place to list it would be a couple of the link aggregators for chan sites [1][2] though if listing there expect a lot of spam and be ready to heavily moderate it. I doubt the HN community would be posting news links to it. As for underground the domain name TLD would need to be .onion assuming one knows how to harden their OS and chan platform.

# do not visit the sites that the following URL's link to from a corporate or family environment.
