Once again your reading comprehension is found to be lacking:
further definition of “automated control of a character in a Game” can be gleaned from the following API documentation:
Neither the API for chat nor the API for invite are listed as protected. Thus it is fair use at any time and thus not considered automation in the aspect of botting.
And before you pounce on the section that does say “granting you and/or any other user an advantage over other players not using such methods;” in 1. Cheats this historically does not pertain to APIs accessible to the player base as it would otherwise describe most if not all Addons.
