Same is true with G+.You're right... exploitation is probably too harsh to explain it since people weren't really exploiting something unintended. People that knew the system and came in with the most knowledge definitely had an advantage in using it and booking more Fastpasses than those who did not. So it rewarded those that came over and over and over again while generally shutting out anyone coming in new that didn't know they had to plan everything out six months in advance.
I will bet you all my DVC points I get more rides per day than the average guest.
So what’s your point ?
