This isn't an easy problem. One thing you could do is mod the moderators. Have each persons vote count a certain amount. People who report true spam you bump up, and people who are abusive get bumped down, perhaps to the point where their opinion doesn't matter. Then require a minimum threshold before you have to deal with it. Also have this ranked against the up votes and popularity.

On imageboard.net we have it setup so more than one person has to mod something down to hide it. It still doesn't work that great, but it's better than nothing.
