Multiple posting of an automated message is spam, whether you paint it differently or not. We're not talking about someone saying "poop", or "dude" but an automated addon announcing the actions of the player in public. The fact that the addon automatically is sending the text without the player prompting it to do so, is an issue in the ToS. Now, see the player continues to send out automated messages, then we're at the peak of, "That is definitely spam". There is a reason for my statement of, "I would report it if it was in the open, unlike in raids, where I couldn't be bothered".
