There have been concerns that some people might use sockpuppets to report their own posts in order to get a reporter badge.

While the above is a real concern, there are also many people who put in a lot of effort into reporting posts without the expectation of receiving any personal benefit. I think it is time to give some kind of recognization to these people. In order to reduce the potential for people reporting their own alts' posts, one option might be to add additional hidden criteria for the various badges, such as posts or threads originally to be in a sufficiently diverse number of subs, or that the result of a report is that the post or thread is sufficiently diverse outcome of removing the post/thread, moving the thread, or editing the post.
