Madwilli commented on this earlier. Similar to his idea it should be (total comments) divided by (negative comments) times 100. example 4/40 times 100= 10% then subtract that from 100 (since that is negative comments) to get likeability. However since most people only comment when they see someone being treated unfairly I think it should take into account the number of games a person has played as well as the likeability of the people who commented
