Fellow curators of @project.hope I think it's fair to ask our participants to self declare if they're going to cross post. I think the community is mature enough to understand the situation and the requirement. And if cross posting to "the other community" is important for their income, they can do it after the payout window of #steem, that's their own problem. There's no term for "self plagiarism", but they will have to deal with their "authority" from the other community which like to downvote everything.
