I recently made a Firefox Extension to mark authors as Slop for the same goal but not the same reason.

I don't think disclosing helps here. If the article wasn't obviously generated, why would that affect you ?

The only issue I have is being half-way through the article and realizing I am reading hallucinated text. If I can mark the author once, I won't see them again. This works fine for me. You could argue that disclosing would fix this issue, but the issue is not that AI was used, but that it was not curated.

Why should they disclose how much AI was used to write an article?
