Sadly I have! I remember when I was hmm... level 25 and at that point I didn't care much about guides. I was in my friend's tribe (I do not know the "friend" in real life) and the next day I left it to make my own. I had left my friend's tribe many times before and no one told me anything. When my friend logged into POTCO he started going on about leaving the guide. So I told him I want to be back in his. And then he ignored me. I went to his server and found him. And then he said a swear word at me so I reported him. Anyways when I was walking away sad, we ran into each other. We stopped and looked at each other. Then I said "I'm sorry, will you forgive me?" and he replied "
Sure, I am sorry for being mean to you!". And that is the end. He never got banned or kicked or anything like that.
