Is bad prose on purpose okay? If you had a character orally tell a story, and their story was bad with redundancies (e.g. a dialogue scene between two characters and every line ends with "[character A/B] says" despite it being so obvious a three-year-old could follow along), is that good writing for portraying the character being a bad storyteller, or is still bad writing in the context of you as the author?
I'm not sure if "ironic shitposting is still shitposting" logic applies here, if it's bad form to make the reader read something poorly-written even if it's done so in-universe.
