The post in the steem blockchain will never disappear but down-voting can hide it softly(we can click the link to see it).
My proposal is add a visibility property of the post. If the creator of the post want it hide, they can hide it by himself.
I know it might be a big change or even impossible. At least, please give it a try. Thanks.
After post, downvote/flag by yourself?
I mean we setup a visibility property for the post. Only author of the post can control it, hide or unhide.
great idea!
