Just a question,
What is this report badges for? Does it affect the ranking system? If yes, Iam sure that lots of user will do reporting excessively even if the reported replies is useful for everyone.
What are the consequences if you do not maintain the report counts?
I think it's just to display how many reports someone has done, and i don't think you really get any other benefits from it..
So no, it shouldn't affect the ranking system, and i don't think that there are any "consequences" for not reporting any posts.
There might be some campaigns that'll pay more if you have made more reports, but i kind of doubt that though.
