You are free to buy votes to increase your potential rewards, others are free to disagree with those rewards and vote accordingly.
What happens if you downvote a post? That user will not invest in bidding and this continues then all of the bots will be running empty.
Sounds good to me.
You are not others, you have the power to turn a profit into a loss. Looks like you are a man on a mission and I need to find other ways to achieve my mission of rewards ;)
