Same with my point about people with intermittent subscriptions counting as at least partial successes for WotC- a yearly subscription is $71.40 right now. Using your example, someone who subscribes for one month every six months is still paying $19.90 per year. And honestly there's a straight mathematical probability that, to the extent that people are actually doing this, for everyone person who's shown up in that list so far who's pulling this trick there ought to be four or five times more who haven't shown up because they're in the a no-subscription period of their cycle.
