OP could have create another account and could make it a legendary account by this time frame without getting noticed by anyone. In an anonymous forum it should not be too hard to stay invisible.

Somewhere I saw few accounts were connected to GreatOrchid. I did not check the credibility but hoping it's not.

Given that this is the only account you have, waiting three and half years to get lifted for a ban and then coming back asking for forgiveness is very rare. It shows the love and passion you have for the account (I am not sure if the passion is same for the community but given the time you waited and coming back it cool).

I think if you should be given a chance.
