The ban is most probably because of plagiarism.

It might haven't been your intention to do plagiarism, but you are supposed to mention the source, which would specify that the content is not your own but is copied from somewhere else.
There can be more in your post history, but as I found this for now, I mentioned this one.

Maybe the original owner of the account scammed someone by selling him a banned account and now the buyer is trying to get it unlocked? It is not hard to scam someone like that since the profile page doesn't show if an account is banned or not if seen by anyone other than the account holder, and the seller can easily scam someone by giving him the profile link to see the account, and the buyer would not know if it is banned.
