The image I chose as an example is from a game called Little Big Planet, and the costume in the screenshot is called "The Bug Blaster".
Ive always had this idea and thought it was cool enough to share.
Making rare and exclusive costumes to those who help the community be a better place for this game would be awesome and rewarding, this will give the chance for moderators to stand out in game and make bug reports actually worth the trouble.
I imagine the system working like this:
Any bug that a person finds and reports that is absolutely gamebreaking (like flying across the map or rendering issues) then the player is deserving of some sort of reward.
Idk, I'm rushing on this idea. Comment some improvements I should make.
