So, I was trying to go to the site, and accidentally searched for "Superuser", and got this.
It routes correctly to this site, but it looks like someone hijacked the search term by submitting with an incorrect cache of the site (or maybe it dates back to a hacking attempt?). Or maybe it's just cached on one of the spam answers? I figured someone would want to know, and possibly submit to DuckDuckGo a more accurate cache.
