Looking at what is happening now with @simplymike and what you have said about the blacklisting. Now putting myself to risk. On a moral stance, I would say this is the same thing which happens in everything which is wrong with society. We have now people fighting with people over votes. The issue is with the bots, You have to wonder why all the time is spent downvoting the user, and not the bot to reduce its power and the attractiveness of using one.
Don't attack the nieghbour attack the invading bot.
