How about weighted votes based on karma? After a certain karma threshold, your vote value is doubled. The system could also have multiple levels. For e.g. at 2k karma, when you upvote/downvote a post, it gains/loses 2 points. At 5k karma, 3 points and so on. Or maybe the user can choose his vote value, limited by his maximum vote value. Perhaps we can also use the average karma somewhere in this equation.

Another suggestion is the ability to downvote submissions after a certain karma threshold. We can use the weighted vote system here as well.

Yet another suggestion is 12 hours/24 hours/1 week bans.

Another problem that I admit facing is the unwillingness to post something with the fear of it not getting upvoted and thus affecting my average karma, even though it might have added value to the discussion.
