Recently i am getting notifications for non-english questions. In my settings my language is selected as English. But notification mails keep coming. How can i stop them?
What you are seeing is a spam post. They abuse every section of AnswerHub and you get notifications regardless of the language it was written in.

Never thought it could be spam. Thank you for banning those guys
