"Your post has also been entered to be included in a daily roundup of positive posts.Please comment 'yes' or 'no' if you feel that my bot is correct in its judgement of this post"
is confusingly worded.
May I offer an edit?
"Your post has also been included in a daily roundup of positive posts. Please comment 'yes' if you think your post is a positive post and you would like to be included, or 'no' if you feel that your post is not a positive post. You may comment "stop" to be added to a list of users that will never be included and will receive no more comments."
Nice, I like that much better as well. The 'stop' portion will take longer to implement but wording is super easy.
Thanks for considering my feedback!
OK - apologies for taking so long, but I've implemented your request. Unfortunately, this will only work for future posts and won't be retroactive, so you'll only get spammed once more. Also, only the original poster can 'unsubscribe'. I imagine it wouldn't be fair for a user that is not the original poster to remove that posts ability to garner additional traffic and receive upvotes. Thanks again for your feedback.
