I don't know how many times it has to be said – that legitimate tourists have nothing to worry about.
You could be using 20 or 30 visa exemptions and you will most likely be allowed in provided that the I.O. is satisfied, based on balance of probabilities, that you are not living here.

I really do think it is that simple guys. You either live here or you don't, and immigration will make that determination not only from the number of entries but your overall personal circumstances. I think this whole immigration drama is getting out of control and has received way more air-time that it deserves. I don't know if it is just me but I'm still seeing posts regarding this matter on my IG/Facebook months later, it's crazy. They're making it sound like coming here is now a roulette spin with double zeros, "will I be let in or out?", when it clearly is not the case.
