Upvotes and downvotes are powers people receive for staking on the Steem network. No one has the authority nor the right to tell you, Smooth or anyone else what they can or cannot do with their upvotes or downvotes. Voting is a matter of subjective stances on issues, and there is no official policy nor should there be an official policy for what you can do and not do with your votes. If there was an official policy that was enforced by a single entity or a power circle, curation would then not be a decentralized system indicating wide community sentiment.
