It is safe unless someone really want to sabo you with some
criminal linking.
Think about it,with the account number,someone can just deposit any
amount of money into your account.If this person commit a crime
that involve a huge amount of money and know he is going to be
caught soon,if he know your account number and has some hatred for
you,he may just deposit a huge sum into your account and then if
caught claim that you are involved in the crime too.Then good luck
to you liao,the police will confirm call you up for investigation
over why such a large sum was deposited into your account
