For all we know the human behind this bot was the one who instructed it to write the original and/or the follow up blog post. I wouldn't be surprised at all to find out that all of this was driven directly by a human. However, even if that's not the case, the blame still 100% lies at the feet of the irresponsible human who let this run wild and then didn't step up when it went off the rails.
Either they are not monitoring their bot (bad) or they are and have chosen to remain silent while _still letting the bot run wild_ (also, very bad).
The most obvious time to solve [0] this was when Scott first posted his article about the whole thing. I find it hard to believe the person behind the bot missed that. They should have reached out, apologized, and shut down their bot.
[0] Yes, there are earlier points they could/should have stepped in but anything after this point is beyond the pale IMHO.
