We review each guest white honestly.
We too have guests that leave the house in pristine condition.
We also have guests who leave it a little messy.
We also have guests who leave it filthy.
We have guests who don't violate any house rules, and still manage to have a great stay.
We have guests who flagrantly violate any or all house rules, and pretend they didn't.
But for each of these, we will rate them appropriately. Not for our own benefit, but for the benefit of future hosts. I would hope others do the same. I think it generally works, because so far, no guests with consistently high ratings have ever been a problem for us.
It's the ones with no ratings that tend to be problematic. We never accept guests with any really bad rating, unless it appears that it's just one out of many good ratings, and the host in that one case was being petty or unreasonable.
Anyway, that's what the ratings system is supposed to achieve. If you just give everybody 5 stars, it defeats the purpose, and might help explain why it isn't working as well as you'd like.
