There are a lot of weird, bad, or outright scammy videogames in Steam.
The platform holders - Valve - are refusing to remove these (or don't want to know that they distribute such content).
This account serves as a collection of most outrageous things which Gabe Newell and co still keep in their store's listings for unknown reasons.
Maybe they indeed support all this stuff.
We, mere end users, never know - and we assume the worst.
