The idea is that the community decides what posts should be submitted into the game so it could be plagiarism, spam, bot abuse or anything really. The person who submits "the case" is stored in a database but never presented to the interface so anybody wanting vengeance won't know where to look (hence the challenge with paying rewards).

The idea that the players of "the game" decide whether something is abuse or not is the human element checking that the technology is working - along with the daily report which gets posted with the "strongest" abuse cases.

The downvotes could be linked to the result of each "game" but I think I'd prefer that to be handled elsewhere - e.g. the report could link to the abusive post and allow for the group downvoting.
