Unclear if they do really. Steam started their current "we allow absolutely everything" policy because they were tired of people making fun of them for constantly banning Japanese games because they think anything anime-style is child porn. Except the actual policy implementation is that Japanese games still get banned, even if they're all-ages and on every other storefront, but now it's also full of Western hentai games. (This is consistent with Steam getting employees from Microsoft, DirectX/Xbox were codenamed on the theme "what's the most racist thing we can say about our Japanese competitors".)
