Ladies and gentlemen! I'm waiting for a response from the admins of the site. Leave your accusations to yourself. As if you're crystal clear people and you've never been wrong. Be care of yourself better and everyone will be happy. 
There's already enough proof that your "friend" really broke a rule. There's no point in waiting for an admin to reply as he/she should most likely just say the same thing. Tell your "friend" to move on as it's extremely unlikely for your "friend"'s account to be unbanned.
