We've blocked the bot after their script malfunctioned and they opened a second issue with exactly the same text (https://github.com/mitmproxy/mitmproxy/issues/5286).
FWIW my reaction was classic "expectations not meeting reality": weeks of work to do (what I thought) was a mutually beneficial helpful thing. I was naively not expecting non-positive responses and was ill prepared when you raised valid concerns I had not considered.
Again, I am working on that and sorry I was passive aggressive to you.
