What's with the three different threads about this, by different OPs, all appearing in the last day?
And to answer the OPs question, the Summoner's Code speaks in generalities, not specifics.
The relevant sections are IV (Enjoy yourself, but not at anyone else's expense) and IX (Lead by example).
The Tribunal community has the job of interpreting the Summoner's Code, and has decided that emote-spam violates it. I agree. Clever reductio ad absurdum arguments about other activities (mostly part of regular gameplay) only make sense if the Tribunal starts banning for those activities. It won't.
