"Anybody who has used Google for search over the past year knows that it lets a lot of LLM-generated spam" I haven't used google for years, so what does it exactly mean?
Google search results are full of garbage pages populated with LLM generated content (the pages exist solely to serve ads and capture search results).
Search spam is not new, but the use of LLMs simplifies the ability to make pages that look like legit content (increasing the likelihood they’ll show up in search results).
Medical ethics tends to prohibit it, especially in a clinical setting. It's seen as doing harm to the patients, which physicians tend to frown on.
I've even heard of some papers on fasting, retrospectives -- which I think aren't technically studies but an aggregation and analysis of patient data, collected from events that have already happened, which patients voluntarily undertook -- that were banned from journals because the results may have 'encouraged harmful behavior.' Don't have any sources on that and it's a memory from like 6-8 years ago though.
