You mentioned that you had 12 posts, how many of these were advertising your 'coupon' or was otherwise advertising? How long have you been logged in for?
All of these 12 posts are full-filled with that message, nothing else.
It is not my decision, but I can't support uinbanning you.
My assumption is that Icoperf was a sockpuppet account used to spam your referral code, and you want to get unbanned so you can continue using your main/higher ranking account. If you disclosed who your main account is, members can make an evaluation if you have contributed enough such that unbanning you would be warranted. Your using a sock puppet to create problems wont do you any favors.
