At the default settings, with age and popularity in the middle, my recommendations are nothing but a list of hentai games.

Not that I don't enjoy the occasional hentai game. I have a number of them in my library, but they're far from my most played games. I even went as far as to exclude all hentai, or even fanservicey titles from my list of most played games. It's still a list of lewd.

My two most played games are No Man's Sky and Skyrim. Does the recommender suggest open world sandbox games? No. Boobs and waifus only. The interactive recommender is based.

I don't mind hentai showing up in my list of recommended games, but my tastes are more varied than that. Something is broken.
