If it's a language thing, make sure you don't accidentally have that language selected in your account settings. You should have "undefined", plus whatever languages you actually speak. Note I don't think you can do this through Liftoff yet so you might need to use the mobile site.
Some stuff probably still gets incorrectly language tagged but I've only seen the occasional non-english post which is what makes me think maybe you've got a wrong setting somewhere if you're seeing a lot of them. Just a thought!
