As first reported by EuroGamer, it appears that, following an investigation by IGN, PlayStation has begun removing some questionable, low-effort titles.
Specifically, the outlet reported that titles by RandomSpin, including the likes of Supermarket Simulator Pro, seemingly no longer exist on the storefront. Indeed, visiting the TrueTrophies page for the game, then following its PSN link leads to an error page on the PlayStation Store where a game page would have existed at one point.
At the same time, however, RandomSpin is just one of several entities filling the PSN with low-effort games. While Supermarket Simulator Pro has ceased to exist, Clothing Supermarket Store Simulator continues to exist alongside Mechanic Supermarket Simulator and other titles.
