So I googled “how to post on stackoverflow with gpt”, and looked for relevant results dating from after the initial rush in December 2022. The first relevant result starting from February 2023, on page 2 of the results, is a Chrome extension, released on 28 February 2023. Going by the demo video, this extension posts the answer a few characters at a time, at the rate a human would type. Someone using this extension would generate a similar number of drafts as a human.
