I fear the day when someone figures out that a well-crafted Show HN post is a great way to get "engagement", and starts marketing to others how to do so or doing it for them.
It's not uncommon to see people showing off their website traffic graph on Twitter after hitting HN. You can also find people asking for advice on how to use HN to market their shitty SaaS on places like reddit.
Another kind of marketing you see quite often is people replying with a post that starts off reasonable, until the third paragraph where the commentator says "this is why we built blah" and makes you feel you are staring at an half eaten Apple with half a worm in it.

IMX, the people submitting LLM slop projects are also, overwhelmingly, making LLM slop Show HN posts. And come across as unlikely to change, or even recognize the faults of the slop they submit.
Which is really not any different from what I've seen on Stack Overflow, or GitHub, or many other places.
