What exactly did you think was going to happen when you make 40 posts a day as a signature campaign participant? In addition to your very high activity/post ratio for a new member, you were copy-pasting replies.
I hope moderators would help me with this matter to unban my account.
It depends on who handles the case. If it were up to me, assuming that this is your first severe strike, 3-6 months minimum is what I'd recommend. We definitely dislike copy-paste.
