No story is perfect, and everyone is at a different skill level, but there's a world of a difference between something flawed an author still worked to their fullest ability on, and something flat out lazy, and it's usually an obvious one. If the writer didn't care, it shows, both in the soulless, low effort, error strewn garbage they crapped out and in their response to valid criticisms.
That said, seeing that even a reasonably intelligent nine year old could manage a story in the three star range without too much difficulty, it would please me if the writers of the one or two star crap could have just that tiny bit of self awareness required to be honest with themselves about the quality of their work. There really is a threshold where the first reaction to a story is just, how on earth can anyone look at this and go 'yes, this is a good and ready for publishing?'
If a story is crap and you know its crap, don't click the publish button.
