My guess is that both Tarrlok and Yakone worked hard to master this dark art. Remember, Hama discovered this on a full moon and simply only did it on a full moon. However just like with anything, someone will come along and try to make it better or more efficient. As a fighting style, bloodbending would not be efficient if it could only be performed on a full moon. A bender like Tarrlok probably worked hard at perfecting the art and thus was able to do it at any time.
