Mandalori

Please someone help me. My account was banned 2 days ago. But I don't know why and I don't find it logical at all. Because I have been playing this game for more than 10 years and I have always paid attention to the rules. Please help me, I want my account back. I'm sure I didn't do anything illegal. If I did it, I did it without realizing it. Please give it another chance.
