This is a straightforward copyright violation. Why is it an issue requiring public shaming? Issue a DMCA takedown notice of the entire site to the site owners and also to http://www.directi.com/ which appears to be hosting the site (via orderbox-dns.com) I think. Then watch the sparks fly.
Please don't listen to this person's call to use something like the DMCA. You've done the right thing, calling them out. Honestly, Hacker News based magazines (like Hacker Monthly, which I subscribe to and enjoy) cater to a very niche market that, I suspect, will hold far greater respect for pointing out their obvious stealing of your design/layout/whatever than you pursuing a legal recourse of action.
I, for one, applaud Hacker Monthly's response and actions. Had they pointed out their sending a DMCA takedown notice, I would have lost respect for them. You're doing the right thing. Stay the course! We're behind you all the way.
