Re the OP's methodology for detecting bots, down in the 7th paragraph they say it's a conservative lower-bound:

- they label everything that failed the anti-GPT test 'bot' and everything else unambiguously 'human' (even if might be inauthentic or compensated human, a non-GPT bot or a bot with some basic input filter to catch anti-bot challenges). For example commenter Emmanuel/@techinnovatorevp doesn't fail the anti-bot test, but posts two chatty word-salad comments 10min apart that contradict each other, so is at minimum inauthentic if not outright bot.

- even allowing there are other LLMs than GPT, or that filtering the input for 'GPT' after an '---END OF TEXT---' to catch anti-bot challenges

- why not label everything in-between as Unconfirmed/Inauthentic/Suspicious/etc.?

- makes you wonder how few unambiguously human, legit accounts are on ProductHunt.
