For those who are interested, various sub-forums scattered throughout the galaxy were at one point not adding to your precious post count. Taboo discovered it, or at least brought it to my attention, and it was fixed a few months back. This means that for some sections, the 'Other Anime/Manga' section for example, you could post a billion times and it wouldn't affect your post count.
Edit: Fun fact, Ivotas has the highest post count on the forum.
