  @ Non-commercial MOOC courses, only benefactor is someone trying to learn language at no cost. Every entry in Wikipedia promotes a idea, historical reference, in some case subjective view point, which is a Promotional activity by def. If you use the Promotional/Spam argument to silence anyone that you wish, it's no better than burning books & censorship with out support. I urge editors to do some research and verify statements and support their assertions with FACTS.
