Do you know why?
Mostly because of the boards in which the number of posts is not counted for your total posts, but this number is not always accurate, I remember that a recount occurred a previous time.

- There are a few rare mod/admin actions which change your real number of posts but neglect to update your post count.
- Errors can occur which can cause it to drift from the real value.
- If your account is fairly old, then previous post-count recounts will have counted your MOVED: redirection topics, even though these are not counted when you make them. I fixed it this time so that these topics are not counted, undoing the previous erroneous recounts.
and example for recount:
I did a global recount of user posts starting yesterday. Your post count had been inaccurate.
Other than signature campaigns, nobody cares about your total post count.
