AI generated reddit post—did I imagine it?

A while back, someone made a post on an AITAH type subreddit, then updated it saying it was generated with AI. Like 3/4 of the comments left after the update were responding to the story as if there wasn't a big bold THIS STORY IS FAKE update at the top. I've been trying to find this post again for weeks, but no variation of "reddit AITAH AI generated post" offers anything useful on any search engines. Am I remembering wrong? Did I dream this up???

UPDATE: Thank you phlegmy for finding the post!
