I hadn't thought about it for spam. And I do agree that moderators would go wack trying to keep everyone happy with tone etc. I've just rarely seen any need to 'call in the calvary' on anything, seems folks rather call each other out when things get heated up or start to go sideways. I rather enjoy passionate, yet courteous, discussions. Makes me think a bit more objectively. I wish the rest of the internet was half as polite as this site...
