To add to what ImpactBreaker posted, the initiate title system at AHS is based on Ayu's songs. Everyone starts out as a "poker face Initiate". After a certain number of posts the rank changes to "YOU Initiate", and so on. Only staff members get custom titles.
Some more discussion of initiate titles is in these threads:
