If you were not caught doing it back then, then you will not likely get banned now if you don’t continue to do it any more.

Mr. Moa is correct, why not just use custom challenges to get to where you want to get.
You shoulda done research buddy. 
The Banhammer doesn’t work retroactively, and you admitting you cheated may just net you a ban manually from an antagonizing Matchmaking Systems guy.
