Too bad Charlie can't come up with a formula to get rid of multiple ID banned rules breakers who flaunt their disregard for CureZone by coming back again and again after being banished - and creating separate IDs to attack people to keep their main ID from being banned. (Is that like robbing a bank with a mask on, and only the mask gets sent to jail?).
If I were such a person I would thank my lucky stars that the rules were not enforced more strictly and the last thing I would do would be continue taking pot shots at old foes who have abided by the rules.
