inactive Account Removal ?

Hey i just got a job at a software company and i probably wont have time to play aion as much though i love this server its so active!, any who i was wondering what conditions do they delete your account or remove it from the server ? whats the time span if you dont log in ? i know it tracks the times you log in.

 

I was left the country for one and half month and my account not suffer anything..So..I think it's not a problem to be inactive..
