The sidebar calls this Most Liked; the page itself is headed Most Reputable Users. They are the same board.
Reading the board
Rank, avatar, display name and total reputation. Top three get a crown, trophy and medal. Rows open the member’s public profile, where their reputation is broken down by trait.Only members with reputation above zero are ranked.
Why this board moves slowly
Reputation is deliberately hard to farm:
Members can also switch reputation off entirely in their privacy settings, and blocking works in both directions.
The practical effect is that climbing this board takes sustained goodwill from many different people rather than a handful of friends.
