您讨厌用户那么多吗?好吧，这取决于您，但请记住:如果您通过为他们服务而赚钱，那么您将迈出至关重要的一步，以销毁您的收入来源.不要争辩是否公平地想要什么；我已经警告过你了.

Do you hate your users that much? Well, it''s up to you, but keep in mind: if you earn some money form serving them, you''re about to make a crucial step to destroy this source of your income. Don''t argue if what you want if fair or not; I already warned you.
