How do I get the "Quality Posts" badge?

Reputation points are given by clicking on the red check mark next to the "Post #" of any given post. A "Good" rating for a post gives the user 10 reputation points, and a "Bad" rating for a post subtracts 10. You must have at least 100 posts to rate others, and you must rate at least 10 other user's posts before you can rate the same person again. You are also limited to 10 votes, or ratings, per day.

This system is designed to only reward the highest quality posters with the badge. Any abuse of the system could result in individual banishment or removal of the reputation system entirely.
