I want to know why my account was blocked
To appeal locked account, log on to the account via website and you'll find an option to appeal.
Lock/Suspension/Appeal will never be discussed on forums.

@Kabtsheno You also need to read our OSM terms where it is clearly stated on point three that having more than one OSM account is not allowed.
Decide which account to keep before you make your appeal.
