Raise the prices of bombs and plat memberships etc. (EDIT: through the karma store that is.) I like that more than adjusting the karma point system.
First, don't change anything about the bookie forum. Thanks mainly to swole, 4everhung, and redguru, that place runs as smoothly as any forum on EF and, as swole mentioned, doesn't contribute to inflation.
I like eat big's idea quoted above. Increasing the price of bombs, etc. would decrease the advantage that high-K people have over the rest if it cost a larger portion of their karma to, say, black out someone's posts. That, ostensibly, is what you're trying to correct with the system.
#6 is completely absurd. Karma/reputation/whatever systems on forums are a reflection of the value creation that occurs when people exchange information, converse, etc.
If one of the things people enjoy about the forum is finding ways to collect karma, I say let them do it as long as they don't negatively impact others in doing so. Karma power seems to be the main culprit in inflation; decreasing the number of hits per day and/or the rate at which K power increases are simple and should be sufficient.
