A Student Uploading Excel Screenshots Got an Unexpected Blocking Message From ChatGPT — 279 Upvotes, 193 Comments Trying to Explain It
An r/ChatGPT user working on a class project by sending Excel screenshots and asking what to do reports hitting an unfamiliar message out of nowhere, at a pace they describe as slower than their normal usage. The thread drew 279 upvotes and 193 comments (0.69 ratio) of people diagnosing whether it was a rate limit, a safety classifier, or an image-upload cap. The exact message text is not recoverable from the post title, so this is best treated as an unverified signal that some throttling or classification boundary is firing on ordinary academic image workflows.
