Some people on Twitter have a serious freeloader mentality. Some, politely enough, use a nickname, sounding somewhat like an order: "You must follow me back, you must add him to the group, I must help him make money, etc." Why should you look in the mirror? Whether you're watching "Mortal's Journey to Immortality" or anime or the real world, everyone is focused on profit. What can you bring to others? There's no such thing as a free lunch.
