I discovered the Disciplined badge -- which you get by deleting your own post with score of 3 or higher. And, I've gone through What is the purpose of the "disciplined" badge? and Description of the "disciplined" badge.
Might some people delete good answers to get this badge? Is there a system or group of moderators which checks when answers, having more than a 3 score, are deleted -- especially if a badge-reward results? (IE: "Gaming the Disciplined badge")
Update:
I am not saying to remove this badge. I just wanted to know if there is a system or moderation tracking deleted answers having 3 or more score.
