So I finally made 1,000 posts. Yay me. Post count doesn't really matter to me but I am a little confused.
Thing is, I don't think I actually MADE 1,000 posts.

I logged out two days ago with my post count not quite at 1,000.
I log in today and find that I have somehow accrued 1,000 posts even though I hadn't posted anything since.

Do quotes attributed to you count towards your post count or do DMs count too? Am I missing something again?
