What to do ? Well how about a group to review the commentators ? These could remove/modify the rating/comment priveliges from anyone who gave out consistently excellent/lousy awards. Alternatively, members could have a fixed quota of rating points to hand out per month. This could be overseen by the same group as above Then we need a group to oversee the reviewers, in order to weed out any signs of unfairness. And so on .. Qui custodiet custodies.
