This types of money making method is called BlackHat; it is a way of making use of a loophole in a system to earn yourself massive amount of money at the expense of the system.
The steemit expects people that signed up with them to create and upload a story or article which other people will read and learn some knowledge but your method does not help in this way by any means.
I wonder how many steemit account shall be created without a story in 1 year when 10 people create an account per day ?
