Giga means those who are completely unregistered, not just inactive. Twisty (I'm assuming) is still registered, though inactive. But some, like craftixen, and perhaps jeroen in /mctop fishing, have been too inactive that their names have been removed from the list of registered people on the server. Giga's point is (and I have verified) that a small percentage of people in mctop are now server-unregistered due to prolonged inactivity, and what'll happen to them if they stay in mctop until V6. Removing them from /mctop will allow recently-active players to move up and earn Vet. On the other hand, they worked their way up there a long time ago just like we're doing now.
