I think it would be great if Runescape had a "Report Good" button, by which players can get good marks for helping other players - telling them where to go, helping them with quests, etc. so that they can offset the black marks that they get for doing bad things. The reason for this is because not all players are bad; I know personally that when I'm having a bad day there are things that I say or do to other players which may hurt them or make them feel bad, and on good days I feel like helping everyone. Additionally, I think that this should in no way be used to make people mods, it should only be used to reduce black marks. What'more is that this can be used by any users, not only those for whom the good is done. This system would work the same way as the Report Abuse system - snapshots are taken of the past 60 seconds and reviewed by Jagex employees.
