When posting proper Cn'C make sure to include a list of pros and cons in the signature. What their next steps are and what you continuously see them doing well. Try to include a rating to help then be inspired and possibly improve faster and in a better way. Users who don't follow this could potentially be infracted after doing this twice. The first time you will be warned and second time you will be infracted. Maximum ban for this will be 1-day. You will be penalized no longer than that for bad Cn'C.
