Nice work and thank you for the write up! Part of me is wondering if your bot is talking to actual humans or other bots (albeit not as advanced) because it seems like they just continue pushing forward with their script as opposed to getting wary.
However, I watch a lot of scam baiting and I've seen a lot of them - even on a live phonecall - be told ridiculously outlandish statements that the scammer will gloss over and return to their script, so I'm not ruling out that it's still a real human...
