There would be a lot of resteeming. Perhaps it could be set to subject to mod approval if necessary based on posts or accounts. It could also be limited the same as cross-posting. You are right though as it does seem more serious and would require more community effort.

One can search for beneficiaries, but not on Steempeak. I bet that will change in their next update. If I find losers are re-posting my stuff I'll downvote it.
