Before that, I didn't know the existence of the user name of DannyHamilton. I just created this account and it didn't take long. Do I have the freedom to create a user name?
I don't for one minute believe that you created this username randomly and without knowing the existence of the original account in question. Claiming so makes this situation look much worse and suspicious in my opinion. Changing n to m is a well known tactic of impostors.
