I have now realized that all games which use Steamworks features (i.e. the majority of modern online games on Steam) potentially download Steam profile images from the same location. My Counter-Strike: Global Offensive question "How to disable profile images?" could share an answer with hundreds of other Steam games.
Could I simply rewrite the question (using CS:GO as an example) and change the tag to "Steam"? This would also increase the chance of getting a decent answer.
