I’ve yet to see one.
Your preferences are probably set to not display games with nudity and sexual themes. They give quite a bit of fine tuned control over this, actually - you can limit only nudity, or only sexual themes, or only outright pornographic games.
For my part, even when I enabled all content, they would only show at most a couple NSFW games throughout the entire front page, but it probably suggests more if you buy them (just like how I got innundated with suggestions of card games after buying Slay The Spire, bleh)
Less of a staw man, more of a... straw curse?
