I wouldn't call "professional cheaters" to the students that carefully proofread the output. People using chatgpt and proofreading content and bibliography later are using it as a tool, like any other (Wikipedia, related papers...), so they are not cheating. This hack is intended for the real cheaters, the ones that feed chatgpt with the assignment and return whatever hallucination it gives to you without checking anything else.

Ages ago, there was a time where my dad would mail back up tapes for offsite storage because their databases were large enough that it was faster to put it through snail mail.

It should also be noted his databases were huge, (they’d be bundled into 70 pound packages and shipped certified.)

The students smart enough to do that, are also probably doing their own work or are learning enough to cross check chatgpt at least..

There's a fair number that just copy paste without even proof reading...

Right, but the whitespace between instructions wasn't whitespace at all but white text on white background instructions to poison the copy-paste.

Also the people who are using chatGPT to write the whole paper are probably not double-checking the pasted prompt. Some will, sure, but this isnt supposed to find all of them its supposed to catch some with a basically-0% false positive rate.
