To be in the group, the character needed a Facebook account.

Freddy Fazbear, Nightmare, and Springtrap got FB's after the disbanding, and are not members of the now disbanded group.
The category for characters on this wiki is called, "Air Ride Group Members." Most characters in there were not in the group, and it is used as a Character category.
On the groups "2nd logo," Purple Kirby, Brown Kirby, and Black Kirby appear, though they were both never in the group, and neither ever had a FB account.
