I can confirm that @tydynrain is human, and NOT a bot ;-) He does comment a lot though :-D But always in a good and meaningful way ;-)
As I am the technical guy behind the BBHbot, I'm of course very interested in your results! I saw that it was the second most identical comment. We've been working hard on battling spam and abuse of our bots (together with @tydynrain, we also have some other tipping bots, such as the indeed bot), and have stopped posting comments from the bots quite soon (I think even first, but not sure). If spotting any issue with these bots, feel free to contact me about it!
I'm interested to see how many of the BBH calls are coming from the same (group of) accounts. One of the issues we had in the past, was a bot, just commenting the tip-call on every post that passed by, even though it didn't have any BBH holdings, and thus no tipping power. Not sure what the idea behind the bot was, but it was spamming like hell, so down the blacklist he went. I might have to do the same again, based on your data!
I could almost write a book in this comment, just by looking at & thinking about your vizualisations (I also work in Data ;-) and was thinking about similar things ;-) ), as it clearly shows a lot of issues. Some of the accounts I saw in the lists are very spammy indeed, even though they may appear human. On the other hand, some may be bots, but have their use (as you mentioned).
Anyway, great work! Love the pictures! Keep it up! Thanks for sharing! !BBH ;-)
