What is Advertising? as in "banned for advertising"

According to my understanding :
It's the promotion of other gaming servers/services/sites,
Self promotion that violates warmane rules:
-Selling accounts
-Selling warmane coins via other sites (scam or not).
-Trying to act on behalf of warmane as in opening a website for selling warmane coins.

section: ADVERTISEMENT OR PROPAGANDA

I asked players on global chat, all had the same perception.
Anything out of this picture?
