Some stats won't be available, since I can't get them (~topics created
Just a thought: you can probably get this if you check which user made the first post in each topic.
The "Unknown Title" shows up for the posts Loyce provided to me. His data didn't include any title, so I would need to scrape everything from zero to get them. New posts and posts which got notified to a bot user have their title.
Most topics have been deleted, so if you scrape those titles, you can skip a few million topics.
