It's not that YOU personally are not producing value, and not that the bot isn't producing value FOR YOU, it's that a bot itself isn't capable of creating value for the community. Even though you set certain parameters it is not curating the content as a human would, so it is essentially spamming the system with upvotes. Unless you are going through and manually reviewing all the upvotes it's not creating real value. It's a simulation. Maybe it gets it right a lot of the time, but ultimately these systems break down because they require human input in order to continue to create real value for humans.
