Its irresponsible to create a downvote bot especially if you are running it without monitoring it. It is irresponsible to run any bot if you arent there watching it as it bots. Downvote bots should NOT exist no matter the reason.

Agreed, except the last sentence. Downvote bots are a necessity to discourage bots that are spamming indiscriminately. If this is only the beginning, the comments on all posts will soon be filled with a ton of auto-posted crap, and the actual real comments from people will get drowned out in the noise. Short of manual moderation by Steemit (which won't happen), what other tool but a downvote is useful?
