I'm not sure your post makes sense.
There's a bit of ambiguity to me:
1. Is a bad report one where you report someone and it gets flagged as bad
OR
2. Where you get reported and have your psots deleted.
The second is already in place with the autoban function (as far as I'm aware) if people make a few posts and are a new user and they get deleted within a certain time limit, they get autobanned. It's nice to look at on the seclog (although I'm not entirely sure if that is what it is or not - could just be hilariousandco clicking his smite button on a load of newb profiles and changing the type of ban to a fancier one

)...
The first is probably a bad idea as theymos seems to want to encourage people to report a lot (as it says on the report to moderator page that it's alright to not have a high percentage).
