When you stay at another place, they have to do TM30 for you, and that automatically ends the TM30 of your previous address. How do you think immigration would know you did return to the previous address?
Ken Gunderson indeed there are no rules that say you cannot come back, but visa exempt is only for tourist use, and living there a long time is not tourist use, that is the rule, and it is up to the individual immigration officer to decide if you are already tourist, that is the loophole.
A lot of other countries solved this kind of problems by saying you can stay for example 90 days in a 180 day period.
