The simple fact that the owner of this bot wanted to remain anonymous and completely unaccountable for their harassment of the author, says everything about the validity of their 'social experiment' and the quality of their character. I'm sure that if the bot was better behaved they would be more than happy to reveal themselves to take credit for a remarkable achievement.
Something like OpenClaw is a WMD for people like this.
"It was a social experiment" has the same energy as "it's just a prank bro", as if that somehow makes it highbrow and not prima facie offensive
I've seen the internet mob in action many times. I'm sympathetic to the operator not outing themself, especially given how far this story spread. A hundred thousand angry strangers with pitchforks isn't the accountability we're looking for.
I found the book So You've Been Publicly Shamed enlightening on this topic.
