So, is it unfair, medieval or even ridiculous? It could be. I'm not saying it is or it is not. Like everybody else, you are entitled to your thoughts and feelings. However, I think you may be confused or maybe even angry about what you think it "should be" versus what it "actually is". From what I've read, people here talked to you about "what it actually is" and, in my opinion, they've nailed both how your suspension probably came to be and what to do exactly about it. They, just like me, probably thought that the most important matter would be to get you back on your cam making money as soon as possible. So, feelings aside, the path has been laid before you.
Regarding support, the multiple emails and the waiting time, again, that is just how it really works. Don't believe it? Take some time to read other posts in this forum or do a quick search on how support teams in any large platform handle their tickets. That should give you a better perspective. No ticket is the same as another, and there are a lot of things happening on support's side that we don't get to see.
There is no easy or kind way to say what I'm going to say next, so I'll say it as it is. Please be aware that I'm not trying to attack nor invalidate what you think and feel or trying to defend the platform. If it sounds harsh, it's because it is.
CB is a private business, not a public institution or government, so rights, fairness, injustice, etc. take on a completely different meaning. A model, any model, doesn't work "for" CB and doesn't work "with" CB (in a traditional sense at least). A model works through their platform. Regarding the latter, the moment you verify your account for streaming, you are accepting and giving consent to operate by their terms and rules. One of the most important terms is, paraphrasing, "We make the rules, we can change said rules at any time, and we reserve the right to restrict or terminate our relationship at any time, with or without cause."
Is it tough? It is. But I prefer, at any time, to be clear myself on how things really work so to know what to expect and do.
So, what's more important for you right now: lifting the suspension or making sure they know they're wrong? Just saying...
