I'm not sure what you're seeing is scraping. There are various services where companies can upload a job posting once and it's automatically posted across multiple job platforms, with LinkedIn being one of them. Formatting often gets lost on the way.
All scraper job sites have low quality inventory eg indeed.
Last time I was looking I used those sites to fil the quota for job applications per day that receiving JSA (social security) requires in the UK - whilst putting the real effort in to the 2-3 decent possibilities a week I found.

No company wants automation played against them, they want automation put to use by them, to benefit them. Hypocrite paradox. It wouldn't be the first one.
The scraped ones are the bad ones. Bad formatting and categorisation, not kept up to date (the job might be expired on the original site but still displayed on LinkedIn) and you have to register and apply on an external site.
It’s quite ironic that LinkedIn is so against scraping despite doing it themselves.
