Advertising for gameplay activities should be done by a WoW player-character who intends to participate in the gameplay activities. This means there should be no cross-realm advertising, and there should be no advertising from non-participating players.
I don’t like “should be” because that doesn’t mean “has to be”.
I vote for a rewrite
“Advertising for gameplay activities must be done by a WoW player-character who intends to participate in the gameplay activities.”
