Thanks for sharing that link! I watched it for maybe a little bit too long, it was a pretty nice implementation of sitting back and watching the world go by.
I have some logic written to detect any calls to bots that have an exclamation mark in front of them. I think some sort of hybrid metric that looks at comment length and complexity (of the language used) will find those that aren't just calling the bot for people to farm the hive engine tokens.
I think the other interesting thing (if it is there in the data) - I can probably work on this as a goal - is ... what was the oldest post that got a comment that week?
Will require me to do one big pull of data from hivesql, or maybe download and interrogate the block log for historical data, but it would definitely be very interesting!
