@tapandrollgames I am not satisfied with our current language filter UX, I can tell you that. But if you have the filters setup in preferences and still see wrong language posts, it's likely because the authors have not set the correct language on their posts, and there is little I can do to fix that.
@Gargron so, I guess the entry on the Wish List would be 'An easy way to report accounts/posts with misidentified languages. But I can definitely see how that is a much bigger task and like quite far down the road, if it is ever to happen at all. Thanks for the response!
