that darknet bot one always confuses me. The artists/programmers/whatever specifically instructed the computer, through the bot, to perform actions that would likely result in breaking the law. It's not a side-effect of some other, legal action which they were trying to accomplish, it's entire purpose was to purchase things on a marketplace known for hosting illegal goods and services.

If I build an autonomous robot that swings a hunk of steel on the end of a chain and then program it to travel to where people are likely to congregate and someone gets hit in the face, I would rightfully be held liable for that.
