Ok I investigated and found that if you go to the very end of the Wyrmrest Accord topics they mostly stop at 2018 (when I thought the changeover happened). But two earlier posts exist for unknown reasons, a year apart. These two guild recruitment posts.
Even those, as mysterious as they are, are significantly younger than 12 years old.
In short there is no rational explanation for this post existing and there is clearly dark sorcery at play
