Exactly. Next time, if you're addressing one person, be considerate to others and yourself and use a private chat channel, like /w. Then you won't have to worry about being reported, unless the other person is that much of a troll.
That's the definition of advertising in this particular case, the reason you're banned. Doesn't matter dead or alive, the point is you are in a way redirecting attention away from warmane and towards another entity. You could use some other communication method(discord/messenger/whatever) where warmane's advertising rule obviously can't apply..
You can try appealing the ban, maybe you'll get lucky.
