I don't think a ban would be seen as ceasing to be a ban just because there are federation glitches right now that causes the ban to fail to be federated (not to be confused with a community you are "banned" from and only your instance can interact with you in), but whatever. You're probably right. Assuming you're even anyone who has been here before.
I cited Snopes too.
This does undermine the OP's point.
