lillominato89 said it would be interesting to scrape the number of posts, what do you think? I can work on it if you think it's a useful statistic
I'd be interested, specifically in the differential between my public and non public posts, which is about half and half these days. My activity/post count has the real numbers I believe, while my lists of posts is the available content. I realise that's probably more than you were suggesting though 
It would mean others users could spy on us Presidents to see how busy we are in forum backrooms 
Don't worries, my friend! There was no espionage mission planned

I simply thought that "Activity" referred to the number of posts written on the forum, but I was mistaken because the post count is actually shown elsewhere in the profile settings, not under the profile picture like on Bitcointalk. That misled me!
I suggested to Babo to include it in the statistics on his site to provide a broader and more complete overview! But definitely not to spy on the president, vice president, chief of staff, party members, or members of the clergy xD (sorry for the joke, I thought it was funny).
If you think it could violate the privacy of the moderators, we can discard my suggestion.
