1. Absolutely not, I did have my tag on. Because he banned through SourceBans, he didn't have to put my name in, just my SteamID. I was in-game as Raven [ibis.a] which you would know if you had watched the demo. Funny enough, it seems he banned me either as or right after we switched maps because the ban doesn't appear in the chat on the demo. I'm going to check the other one to make sure.
2. The rule still stands. Admins are not to ban other admins.
