I'm just full of ideas today. :P
Not quite the same report button as this question: http://pokemondb.net/pokebase/meta/1200/i-suggest-a-report-button.
The idea would be that if you saw something like a repeat question, a bad answer, etc, that the button would be there, and there would be an icon on that question indicating it has been reported. That way, one of the editors can take a look at it, and if it should be hidden, then it can be done. If not, then we could just remove the report icon and leave it as is. This would make it a lot easier to see questions aside from ones that are voted down. (It's a lot harder to see the answers since you actually have to look at the question.)
