A ticket can be opened to support. The reason will only be given to the account holder, so when opening the ticket, included the account name and e-mail address used on the account.

edit: I didn't catch you opened a ticket.
The diamond level account we opened for our son (11 years old) as a birthday gift has been disabled without any notice or indication as to the reason. A couple of hours ago he was playing, and now his account appears to be locked. No notice, no reason given.
He LOVES chess, plays every day, and this has been a wonderful learning tool for him. I understand that this account could be disabled for cheating or other violations but we know that isn't the case ... he's just a kid who loves chess.
Has this happened to others? I've opened a support ticket but still am amazed that this could happen without any warning. Any advice from other parents?
Thanks and regards,
Chris
