英文翻译On Baidu Tieba, a "fifteen-character" reply is a meaningless post deliberately padded out to exactly fifteen Chinese characters, done purely to farm experience points and boost one's account level. Users post such filler comments as a way of grinding out activity rewards rather than contributing anything to the discussion.
