I think it would be useful if reviewers could mark posts on the
/review page as reviewed and found acceptable. The marked posts would then be hidden from the reviewing user. If enough reviewers (3-5) mark a post as reviewed, it should be removed from the
/review page for everyone.
This would make it easier to spot the problematic posts, as not everybody has to review every post. It would minimize the duplication of effort and make the whole process more efficient.
There should probably be a reputation limit on this power, I'd say 3k as I would rate that responsibility similar to close votes. Moderators could get deciding votes there, as they already get for close votes.
