If you believe the Bitcoin blockchain would not work if miners could spend the reward of blocks as many times as they would like, you should also believe the same of the rewards given to Steemit posts.
To me this is two very different things. It is not one person taking from the reward pool. It is a group of people giving to that person a reward. The Author of a post demands nothing from the people. The miner demands from the people payment. two very different things.
I like what , and steemcleaners, and you do. But reading your post and thinking about it, all that would be allowed on steemit are pictures of peoples cats, that have not been posted elsewhere on the internet. Reading your post I got the feel that if it is published or posted anywhere, ie:Internet, newspaper, video, magazine, or newspaper or anywhere else that stuff gets "Published", it would not be allowed to receive a vote for a Reward on Steemit. sorry, that was how I read and interpreted it.
