Let's take it one step at a time.
You say you know for a fact that you didn't break any rule in regards to management of your team. you also say that every fine you got was related to something you wrote in the forum.
I think your mistake is that you think that the forum is not a part of this game...
Users who breaks the rules of the forum may be fined / banned from the game. Banning only from the forum is also a possible punishment, but it's case by case. (And I won't discuss any specific case)
Let me refer you to the rules:
K, so now for the tough part. The conferences are moderated by our GMs and moderators. When posting in a public conference, you are expected to remain polite and refrain from either personal attacks or political discussions. Further, you are expected to keep your posts on-topic; there are Non-BB folders available for discussion that does not relate to BuzzerBeater, for example. Any messages deemed spam are also prohibited. In most forums, there are additional forum rules posted in a sticky thread. Posts not in the language(s) of the forum will also be removed so that everybody can read all discussions. If there is no folder available for the discussion you want to have in the language you want to have, please tell one of the GMs and we can create a new folder for you.
Users who do not behave properly in forums may be banned from the conferences for some period of time, banned permanently, fined, and/or in extreme circumstances, even banned from BuzzerBeater entirely. The forums are an important part of the community, and we are committed to keeping the forums friendly and welcoming to all of our users.
