Note: it is possible to get a "banned" alert if you use an IP which was banned previously (it could be a proxy, or VPN, or even a legit residential IP if it is distributed as dynamic IP).
I asked when was the ban because I checked the last couple of days in the logs (they are public, home page has the link to them) and I've found no ban with the reason "real spam".
