Similar experience here. The idea was mine but I wanted to get proof read and correction using AI and posted comment, but it was blocked because it is written by AI. Maybe I'm half guilty, but wondering what is definition if 'AI written'. If idea is mine, can I argue it is still my writing? Or if I get any of AI help it is AI writing?

this message of yours isn't AI written. but if it was, it wouldn't sound confusingly human. It would sound like AI.

You can't blame people for not liking what you write or pretend to.
