I was thinking the same, there are known automated strategies to catch copy cats or just bad writing.

However I’m guessing having a big inventory is more valuable than quality. That could be amazon’s cultural motivation to dismiss quality by default

The scam books are not just "bad writing" and usually don't rip off other works; many of them are filled with pure garbage: random letters that form non-words.

But maybe you're right, the size of the inventory is what matters to Amazon who may be stuck in a "growth at all costs" mentality. That would explain it in part.

That should make it even easier. If X number of words don’t appear in a dictionary, then it’s a scam. Amazon also has a natural language processing platform. If it can’t parse X percentage of sentences, it’s a scam.
