So, you obviously use multiple accounts on there.
But what do you mean when you say "my Mom's account was totally emptied of over $1,000 worth of bitcoin"? you still have access to the account (So, you are not suspended/restricted). look at transaction history, maybe someone hacked that account and regularly withdrew Bitcoins from there.
