I appreciate this topic being discussed and was feeling upset about it myself until I encountered this post about the Cheetah bot a few days ago: https://steemit.com/steemit/@anyx/cheetah-bot-the-fight-against-spam-and-plagiarism-continues

It made me feel better to know that the conversation is happening and has been. For more, consider searching the "bots" page and finding those who are running bots for the good of the community and reading their comments. Hopefully, you'll discover that the topic is bigger than it seems and that while some of the behavior you've described is certainly what it appears, it isn't going unnoticed.
