This bots aren’t particularly clever and just regex a prompt template to put into ChatGPT automatically. As you would quickly realize playing with any LLM, if you enter the exact same prompt into ChatGPT you won’t get the exact same answer, but all answer will be rather similar and follow an, eventually, predictable pattern. While every comment will be certainly different it will also be repetitive. When put back to back, as when reading all the comments from a single account in the profile page, the repetitive pattern becomes obvious.
