N3O does not normally accept re-applications of this manner; that expectation is outlined in the rules of the clan one accepts when one joins.
The fact you recently applied/joined another clan does not sit well with the clan. Also the fact that you made a big fair well post about going to study and such does not help your case either. Nor does you giving your account to another individual who acted very immature.
The final decision will be made once the officers have a discussion, but it is unlikely N3O would accept a re-application at this point in time.
You do know that you are not blocked from participating in games with clan members (unless you upset Lazy and get pested ). As a non-clan member, you may get bumped from time to time for a clan member in a game. Friendly, mature participation in games as a friend of some of the clan members can only help your long term prospects for re-admission, and my guess is that you should be thinking long term here.
