I have had multiple complaints about people noticing their post count going down. At first I thought it was due to deletes and such, but I started to poke in the database and sure enough, I think they are correct. Using my user_id, my message_count in xf_user is hundreds of posts lower than the count of posts I have made in xf_post or xf_thread_user_post. I've been digging into the source to try to find where the xf_user.message_count is updated, but I haven't been able to find it yet. Any insight?
