I'm interested in why you feel like this. Do you take this action because you can't trust traditional channels (blogs, established tradpub authors, Goodreads et al) to self-curate LLM writing out of the pool of available literature you would normally be aware of?
Yeah I think it boils down to trust issues. I can't know how the text was created. Anything created before 2023 I know that at least a human had to invest a significant amount of time to produce the story.
Maybe I'm a bit too reactionary though. Thinking about it some more I would absolutely read something if it was recommended by a trusted source (which in my case is almost always a human I know in the physical world).
I get the sentiment completely. I am actually doing what you're thinking: if it didn't come from my List Of People Who Know Of What They Speak I want nothing to do with it.
We really have gone full circle! It's quite upsetting.
