For example, with a users set to 10 and new-user-every set to 15:
 * UnrealIRCd will remember up to 10 users that the user is messaging
 * The user can /MSG the first 10 users without any problem (eg: k1, k2, k3, k4, k5, k6, k7, k8, k9, k10)
 * When trying to send a message to the 11th user (eg: k11) the user will have to wait up to 15 seconds before (s)he can do.
 * Then the user can message the 11th user (k11)
 * If the user then wants to send a message to a 12th user (k12, or even user k1 again which has by now dropped of the active 10 users list) then (s)he has to wait 15 seconds again
