If ten people were on the reward pool of 110 Steem and each had 10 each. When you vote you can use your vote of ten to dissolve one persons account to zero (negative direct action against something you don't like) or upvote one other post by 10 meaning your favourite post eaens double which is positive action. The others will also 1/10th less of the reward pool compared to you not having voted. So you're right that if your intention is purely negative it is less direct... But the effect on the post you like is explosive making it double. So you have the choice of negating the positive upvote someone gave to a post you didn't like (is it your business to act like that?) or you can upvote to a post you like meaning the author is encouraged and visibility increased attracting attention to it of other voters. I come across countless posts Im not impressed with or interested in but I'd never use my Steem power to tread on those specific interests. There was a time that guys here were sick of pretty girls getting high rewards for posting make up tutorials. Should we all Gang up and downvote them? I think everyone should stop worrying about their self centered connection to the reward pool and concentrate on good posts and good comments for what ever audience they find and attract. Live and let live
