Add Achievement for Correct Spam Report

Hi,

Achievement is a fun way to show you are active in the forum and did something. It would be nice if you could add Achievement badge for those who reported spam posts and they consider as spam and has been blocked. It could be like when a user reports a number of correct spam (they verified as spam and removed), then they receive this achievement. It is not about number of reports but rather number of correct reports. This will motivate other users to report spams and help community to become smarter.
