There could be something preventing you from unthinkingly click “Yes”, akin to the option in LeechBlock whereby you have to copy a code of 32/64/128 random characters before being able to change the settings. (But that might backfire, by discouraging people from posting comments even when they would be unobjectionable.)
Or perhaps there could be an option to click “I am sure this comment is useful and harmless” when sending a comment. A comment without this option gets +1 karma on upvote and −1 on downvote; a comment with this option gets +2 on upvote and −5 on downvote. This could make people think before posting.

I would love that.
