Fish,

Notwithstanding your right to choose who, and what, you trust, it's not very considerate to publish your irrational fears as a warning to others.

Here's a challenge for you:-

Choose a bank, any bank in any country (or 100 banks in 100 countries), write to the manager/s and ask if it is possible for ANY person in possession of your full bank account details (save and except for passwords, code words and PINs) to, in any way shape or form, interfere with your account.

If you receive any affirmations, publish the result/s on this forum together with a warning that all and sundry should ignore the misguided and patently wrong utterances of Wuxi Guy. :-)
