#11 SpamFilterDummyUser

[Luma Prianca Salman]

Code Smel: Large Class
Location: birdsong.dummy.SpamFilterDummy
Refactoring: I noted the existence of several instance variables,
usually it indicates that a class is trying to do many things. So decide extract RemoveBanUsers () method to a new class called SpamFilterDummyUsersRemoved using the Extract Class refactoring.
