Can anyone explain how the ?Social Star? ratings works with Home Design?

[TrixiDeCat]

I have never seen any game with such an insane social rating scheme. It is crazy. I visit my neighbors with social ratings of SIX but as I click likes their social rating drops with every click. A neighbor with a social rating of SIX can drop to ONE depending on how many likes I click / are available. If someone is full and no likes are available, their social rating remains untarnished. I have absolutely no idea how my social rating appears to my neighbors. I can visit every neighbor I have (and community members) but my rating never exceeds 4. There is more...When my rating occasionally drops to 3, I can see the accumulation bar. But as soon as I reach FOUR, the bar disappears and all I see is a cheesy DOS text 4. In other words, the accumulation bar disappears and all I see is a plain 4.
Does anyone else see the same thing? What is the deal? (I am playing on an IPAD version 2 or 3.)
