I have another thought, how about adding "Reports" under "Posts"? this badge idea is actually brilliant and I hope that in the next few days you could find the best design to properly implement it, but having (good) reports added under our forum names also could do the job, it might even provide more incentive for people to compete and have a bigger report count.

Just my zero satoshi.
Disclaimer: this is my idea but if somebody else has already suggested this please don't ban me for plagiarising, I might have picked this idea from somewhere but this post is from my head. also you should ignore the redacted part, that's something which I wish we could also implement but this is not the place to discuss it.
