Voting already is the community moderation system in action! And down-votes are part of that as much as up votes; or would you also require up-votes getting reviewed?
Unlike voting down on answers, which also causes the voter to lose a point, voting down on questions is free in that regard and encouraged. The Stack Exchange philosophy is that voting on questions in general and even voting down is a good thingTM.
The voting system is also already regulated in a number of ways:
- The voting down is a privilege that needs to be earned, it is not given freely, but requires a certain amount of community participation.
- One user, one vote (per question and per answer). The community should easily be able to balance out a single discordant vote and commonly does so too.
