You didn't get banned.
As far as your friend goes, he could've easily price checked CC before trying to sell it.
You said multiple times you didn't care about getting banned, but here you are and you keep whining. Just deal with it. The rule is perfectly fine. Something tells me your friend is your second account and that is why you are so upset. Either way, it is what it is.
