Horrible and arrogant behavior by the appeals committee. Below is the response that they sent on one of my son's account. He is just a beginner who is starting to learn chess and like to practice games on lichess because his coaching academy uses this site to teach him. Not sure why they dont want to allow new players who is learning to make couple of mistakes. If they are not comfortable, they can just restrict beginners from playing rated games. But these people are so arrogant that they decided to block the accounts permanently.
