The problem with all these lists is the editor assigns the same topic every year and they don't want to list the same runs/towns/resorts every year, so they just end up throwing stuff on a piece of paper to see what works in terms of: not listed last time, geographically diverse, and sort of meets the objective. So you might not find green runs on this list, but beyond that eventually every black is fair game.
I think the problem comes up to lack of basic knowledge and lack of effort.
If somebody really cared about compiling a list that made sense and wasn't just terribly researched clickbait, the way to do it would be to compile a list of mountains known to have some of the most difficult terrain. Mountains like:
Then, you make a 5 minute call to the marketing director (or pretty much anybody at the ski area) and ask what the nastiest named run at the resort is. 45 minutes later, you have a great list that doesn't do stupid things like list runs that aren't anywhere close to the most difficult at their areas.
You may miss some good additions from areas you missed in your calls, but at least you have a defendable list. The fact that nobody seems to do this tells me that nobody is spending even 45 minutes putting clickbait like this together.
