They are not rare. They are just in different servers mostly doing guild activities. They are the number one guild of all time in rank Enemies defeated, Ships sunk, Blackjack hands won, and poker hands won and they rules do not require ranking at all from members. Most of them do it for fun but they are a multiple activity guild meaning members can do what they want as long as guild rules are not broken. I don't know many in their guild nor do i play with them but i know that they are very organized with a great leadership on top of it who have fun.
