Ratings Given And Received

Can anyone direct me to a place on the Christian Forum website that states the purposes behind having "Given and Received Ratings"? These are the ratings such as "Winner", "Informative", "Prayers", "Optimistic", "Like", "Agree", etc. I can think of some good purposes in having these (appreciation, a form of communication, encouragement, etc), and I can think of some obstacles they might raise for some (spiritual pride, envy, wrongful comparison [ 2 Corinthians 10:12 ], carnality [being of the flesh or sinful nature], etc. ). I use this blog to ask this question for my own better understanding, and perhaps to be of help to others that may have wrestled with this issue as well. May we strive to use the ratings for the good purposes, and be on guard against the obstacles I have stated as well, to the glory of God, and to the blessings of readers and writers of this site.
