AI might be overkill? I recall back in the day people working out which images where manipulated by the way the underlying flow of colour and pixel layout didn’t line up, each image ends up with a kind of grain of different size and direction. You could spot ads by detecting which image data doesn’t line up with the majority and cutting it out that way.
To be fair thats what happens when essays have minnimum word counts, long essays that are long because they don’t know the topic well and long essays that are passionate and succinct and then padded out to meet the length requirement.
