B. to put up; should be
C. being put up
(答案→)D. putting up; be
解析：本句可以转化为：All the citizens here strongly insist those who was found putting up “harmful” advertisement in the streets （should） be punished strictly. 第一空考查find sb doing sth的被动语态的形式，第二空考查should +动词原形的形式，should可以被省略。句意：这里所有的居民强烈要求那些被发现在大街上贴有害广告的人应该受到严厉地惩罚。
