TopFavor
TopFavor or Who Favors Who? is a tool that uses the Profile name filter to show two top lists.
The first top list shows the 100 users that have given most Favorite points to the user's caches and how many favorite points they have given out. It also states how many favorite points the user has gotten in total and on how many caches plus the average of favorite points per cache.
The other top list shows the 100 cache owners that the user have given the most favorite points to and the number of favorite points. It also states how many of their potential favorite points they have given out and what percentage that is.
