Thanks, yes have chatted to @jesta before and he's been very helpful. Haven't as yet had a response on this issue, will try the chatrooms again.

It is difficult to balance the positive and negative algorithms - sometimes they are just not symmetrical, so that trying to invert the algorithm by, say, to improve rewards for collaborative exchanges compared to small cliques runs into other problems of scaling up rewards (potentially with no ceiling) rather than scaling down self-voting/clique-voting behaviour which has a natural floor. Don't know if that is clear - so one has to sell the positive effects of what appears to be a punitive algorithm when it's aim is to encourage positive behaviour.
