I got 1 downvote a few days ago and I reviewed my post if I violated any policy. Then I saw a post from another user telling that she also got downvotes and even her friends got downvotes even as far as they know they didn't violated any policy. I hope someone could answer this.
Downvote occurs when from Upvote, our post can be downvoted if it is considered doing plagiarism and copy paste or trace, or disliked by others who have a large SP (steempower) and it is very influential.
Flagging occurs when content is offensive and offensive and rewards the rewards we receive, many flag rewards, with Steem Power owned by someone, by flagging, in an instant rewards to $ 0.00.
There has been a flag bot made by a few madmen. It's okay that they do not have voting power.
jealousy , people are downvoting others because they dont see other earning money and they are not. because if you didnt like the content , you can directly comment and said why you didnt like a post but downvoting someone's effort is definitely not the right option,
