Welcome to 'Know Your Site' a (hopefully) every Monday Worldbuilding trivia feature where I use the Stack Exchange Data Explorer and maybe some python parsing to find out interesting things about the site.
I will post a question on Monday, and people have until Thursday at noon to guess the answer! To be clear, using the Data Explorer to get the answer is cheating. If you use that to find the answer, feel good about your inherent superiority, but don't post it! Also, absolutely do not look at my Data Explorer profile, because that is definitely cheating.
Which users have posted the most total value of bounties on Worldbuilding?
Name the top three in order to win!
Side note: If you have any good ideas about awards for the winner, please post to comments.
