People have different expectations of a bot because they know that a bot is being told what to do by someone else and that the bot does not understand its impact on others. When "normal" users post things online they can be held accountable as they have a basic understanding of what they are posting and how it can affect others. A good example of this is the case of Justine Sacco and her racist tweet.

This article/source was about a women who was allegedly using a hundred or so iPhones to delete and reinstall specific apps on the phones in order to get that apps download count up. Apps with a higher download count receive a higher ranking in the App Store. According to the article this has been a continued issue for Apple and you can supposedly pay groups of people thousands of dollars to get your app into the top ten apps for a week.

To add on to this description of Consequentialism ethics, it is also about maximizing the good, meaning that the morally right action would be the one that has the greatest net balance of good over evil. A common criticism of this ethic framework is that the idea of "the ends justify the means" can sometimes hurt minorities if the result is deemed beneficial to the majority.

I think that one feature on Twitter that allowed these events to happen is that you are able to retweet the post and share it to your followers. Even if Justine only had a few followers, one of them could have thousands and when the post was retweeted, more and more people saw the post and most likely also retweeted it which continued the cycle. Another feature of the app that enabled the events is how public her information was. People were able to see exactly where she was and could figure out where she was going which lead to photos of her coming off the plane to e taken and spread online.
