There used to be a screen, at least in the FB version, where it would show 8 random friends and "Stuck for xxx days" below their name. However, now that info is replaced with the level they are currently stuck on.

In my personal case, I ask for tickets to the people that send me requests more often. That sort of gives me a guideline on whether they are active or not.

(Again, excuse my English, I hope I somehow made myself clear)
