A senator for the US government has urged Valve to answer complaints about the amount of racist, sexist and otherwise hateful posts and imagery shared by users on Steam. The digital store was the subject of a report by the Anti-Defamation League last week, which claimed to find millions of examples of "hateful or extremist" language and images hosted on Steam's community. These include things like Nazi symbols in profile pictures, white supremacist slogans in group names, and yet more discriminatory spew in user posts.
