There are a few members of Stack Overflow especially who have a ridiculous number of helpful flags.
At the moment, there does not appear to be any way to display the top users with the most helpful flags. Even though this information is already available publicly, there does not seem to be any way to query all users and make a custom leaderboard, using SEDE, or other programming tools.
A quick search on main META did not yield anything related to this topic.
This is not limited to Stack Overflow (although that site will no doubt prove to be the most voluminous).
Is there any way to see a short list of top flaggers on the Stack Exchange sites?
See this? This is what I'm talking about! Totally awesome.
