If you hire friends when you explore rooms, then they may be kept on the list for that purpose. You can even be picky and delete all but the keepers or accountants (whatever your preference). It is possible that some active players may never open up the event rooms and thus get flagged as "inactive", so you may want to see if their rank changes over time.

(If you don't hire friends, you might want to look into it. This provides you with a benefit at no cost other than a few clicks.)

Otherwise, go ahead and remove from your list.
