More importantly, armorsmiths are STILL exploiting this on TP. People, unknowing of this bug (as is the case of the original poster), buy these boxes thinking what a great deal they are getting, but it’s the exact opposite.
I do not even think the armorsmiths can get punished, since they can simply claim that they could not know what these boxes contained and that they did not discover the recipe for the rare one (which requires the same materials according ot gw2db and guildhead).
