Thanks for taking the time to post. You've put a lot of effort into that message. You're through to the forum team unfortunately. Here on Answers HQ, we won't know why your EA account might be banned and we cannot effect the outcome of a ban appeal either, sorry. You're looking for the Terms of Service team, they would exclusively help and discuss ban cases. If you believe there's been some sort of mix-up with the application of a ban, they can be reached by filling out the webform (that sends in an appeal to them).
You might be able to get some context in the meantime by taking a look through your emails for a message from them. They aim to send one out when a ban has been added. It may specify the general rule broken, for example: ban applied for cheating/hacking/hate speech/etc. For more on those, this article may help: "Play by the rules in Apex Legends
