I've had down votes before, and i simply request the reason as to why "said person" has Downvoted me and that has always resolved the issue, however im not sure how it works with BOTS, iv'e never, and hope to never have this issue, im sorry for the bothersome activity, the fact that you set a bounty for this and are asking the community for help with extensive reasoning behind your complaint should prove that you are not spamming, or trying to deceive anyone. Best of Luck to you, im sure it'll all work out in the end!
