They downvoted multiple posts and all comments 12 hours before payout. This indicates a targeted action to reduce all rewards without time to re-upvote or address grievance. It's possible the remaining posts will be flagged in that timeframe. Without any communication from the account clarifying their actions it's not worth the time and effort to facilitate the contests with risk of flags negating payouts and losing my paid upvote investments.

I asked about downvotes on discord and they say that "reward farming. Up voting to enter a contest for a share of the post rewards is abuse." "These are Steemits rules"

So don't write in the rules about the need of upvotes

My contests don't require upvotes. Each post informs that contestants may upvote my comment or post their own comment to receive rewards. The rules state that upvoting will increase a contestants share of rewards as the prize pool grows in proportion to their vote values. Additionally, @votum is not created by or associated with steemit, and there are many contests posted by other accounts that require upvotes and are not flagged, so that explanation doesn't make sense to me.

Thanks for the update. I do not connect to private discord servers but have left a message on his post.
