I think I asked this before, but I'm not sure what the answer was..

Could a penalty for spamming be subtracting Goop? Each post gets you like 5 points or something, so maybe if it is really noticeable that the person is spamming, there could be like a 100 point penalty for each offense. I'm not sure if this sounds like a good idea at all, but it would be less severe than a ban, and the members wouldn't revolt as much against it: They would simply try to stop, for fear that more Goop would be taken away.
