I'm flagged because of coping from myself!

in the last starters contest, i planned to start a new account for my professional career but unfortunately i realized lately that its a violation of code of conduct to have two accounts. in the mid of contest, i once referred it and then decided to continue back with my account as its wrong to have so. i just copy pasted the code that i submitted in new account with changing the name space to continue the contest with old account!..

its me only right! i genuinely wrote the code, I’m flagged for doing it so.
now i will delete the other account .please help me how can i explain the chef that its not knowingly done. excuse for once and last time.
