I get what you're saying here and I agree if you're only using unedited AI content to just increase your post frequency, then yeah it's annoying and feels somewhat abusive.

I personally like to use AI to make a first draft and then edit from there. It's way faster at that first draft than I am, but I can still maintain my voice and ensure I'm making all my points.

I will say many people are also generally bad writers. Is it slop if it's actually a better writer than the engineer making the site or the owner of a small business without a marketing team? It just seems like a tool to write better.
